Respiratory and Endocrine System Flashcards
The Respiratory System is also called …
The Pulmonary System
Main function of the respiratory system
Supply oxygen to the body’s cells and remove carbon dioxide.
CPR
cardiopulmonary resucitation
External respiration
When you breathe in, oxygen is brought into the lungs for the blood to pick up.
When you breathe out, you blow out carbon dioxide that has moved from the blood to the lungs.
Internal Respiration (Cellular Respiration)
Is parallel to the process involved in external respiration, but conducted at the cellular level.
Procces of Internal Respiration
After blood passing through the lungs picks up oxygen, the heart pumps the blood to the rest of the body.
The oxygen passes through the capillary walls and into the interstitial space, where the cells absorb the oxygen.
The cells release carbon dioxide as a byproduct of metabolism.
This carbon dioxide waste is picked up by the bloodstream and carried to the lungs for expiration.
The respiratory system is comprised of…
- Nose
- Pharynx
- Larynx
- Trachea
- Bronchi
- Lungs
- Diaphragm
Two main jobs of the nose
- Provides out bodies with warm, moistened oxygen.
- Holds the olfactory nerve that enables us to smell.
Inspiration
The movement of air into the lungs
The advantage of breathing through the nose:
- Warms, moistens, and filters air
(External nares are lined with mucous membranes and short, coarse hairs (cilia) that filter out foreign particles.
Mucus kills some germs and stops the growth of others.
Pharynx
Multipurpose tube leading from the back of the nose and mouth, down to the trachea (windpipe) and to the esophagus.
It allows air to reach your lungs and food to reach your stomach.
Larynx
Located between the pharynx and trachea. It’s also called the voice box because it houses the vocal cords.
Vocal cords are though bands of ligamentous tissue that vibrate to produce speech.
The size and tightness of the vocal cords determine the sound of your voice.
Glottis
The space between the vocal cords
Epiglottis
A leaf-shaped flap on top of the larynx, is responsible for sealing off the airway to the lungs when you swallow food or water.
Trachea
A long, hollow, smooth muscle tube that runs down the chest in front of the esophagus.
The trachea separates the upper respiratory system (above the neck) from the lower respiratory system (below the neck).
Those who are severely ill, undergoing surgery, or in an emergency situation can receive continuous, artificial ventilation by having a mechanical ventilator connected directly to the trachea- either through the mouth or by puncturing the skin in the neck area.
The ventilator then pushes and pulls air in and out of the lungs to continue supplying oxygen and removing carbon dioxide.
The trachea branches off into two main bronchi, and then the bronchi branch off to several bronchioles.
Bronchi (singular bronchus)
Lead to the right and left lungs.
After entering the lungs, the bronchi continue branching into smaller and smaller airways.
The smallest ones are called bronchioles.
alveoli (plural)
alveolus (singular)
The bronchioles open out into balloon-like pouches
Each alveolus (singular) expands and contracts with each inhalation or exhalation of air.
Capillary beds
contain the smallest blood vessels of the lungs, and they lie next to the thin tissue membranes of the alveoli.
Here, oxygen from the alveoli combines with hemoglobin, a protein in the red blood cells, and is carried to all parts of the body.
At the same time, carbon dioxide is transferred to the alveoli to be discarded by the body when you breathe out.
Right Lung…
Divided into three lobes.
Accommodates the liver.
Left lung…
Divided into two lobes.
Has a notch in it to accommodate the heart.
Heart and lungs are protected by…
Chest wall.
Diaphragm
Sits at the bottom of the lungs.
Each breath initiated by movement of diaphragm, internal and external intercostal muscles.
Upper respiratory system includes
- Nose
- Pharynx
- Larynx
- Trachea
Lower respiratory system includes
- Bronchi
- Bronchioles
- Lungs
Asthma
A chronic lower respiratory disease. It involves airway obstruction due to inflammation.
Is triggered by many things, including exercise, allergens, or cold weather.
Chronic obstructive pulmonary disease or COPD
the progressive inflammation and destruction of the lungs. Cigarette smoking is the leading cause of COPD. It can also be caused by long-term exposure to contaminants, such as chemical fumes.
There are two main conditions associated with COPD: emphysema and chronic obstructive bronchitis.
Emphysema is a condition in which the walls between the alveoli are damaged and become floppy.
Chronic obstructive bronchitis is a condition in which the airway linings are thickened because of chronic irritation.
Most people with COPD have both conditions, which is why they’re combined in the COPD diagnosis.
Emphysema
a condition in which the walls between the alveoli are damaged and become floppy
Chronic obstructive bronchitis
A condition in which the airway linings are thickened because of chronic irritation.
Main symptoms of asthma and COPD
Difficulty in breathing
COPD and asthma are treated with
Same medications.
The best treatment option for sudden onset asthma symptoms is using a metered dose inhaler, or MDI, which provides a single dose of medication in a pressurized burst.
Respiratory system diseases are divided into
Upper and lower respiratory disorders
Upper respiratory disorders
Cold
Flu
Lower respiratory disorders
Asthma
COPD
Bronchitis
Pneumonia
Common Cold
Viral disease
Highly contagious
Treated with medication for symptom management.
The symptoms of the common cold include:
Scratchy or sore throat
Nasal congestion, sneezing, sniffling, or runny nose
Chest congestion
Cough (productive or nonproductive)
Body aches
Tiredness
Fever (most common in children)
Decongestants
- Used to dry excessive mucus and open up the nasal passageway.
- Most are OTC
- Side effects dryness of mouth and wakefulness
Common decongestant medications
- Pseudoephedrine (Sudafed)
- Phenylephrine (Sudafed PE)
- Oxymetazoline (Afrin)- nasal drops
Antihistamines
Treat symptoms such as runny nose, sneezing, and sore throat.
Antihistamines are classified as first generation and second generation.
First-generation antihistamines
Target more general receptors in the central nervous system and have more side effects than second generation antihistamines.
Examples of first-generation antihistamines are:
Diphenhydramine (Benadryl)
Hydroxyzine (Atarax, Vistaril)
Brompheniramine (Bromax)
Chlorpheniramine (Chlor-Trimeton)
Azelastine (Astelin)- Nasal spray

Taken only once or twice daily.
Examples of second-generation antihistamines are:
Fexofenadine (Allegra)
Loratadine (Claratin)
Desloratadine (Clarinex)- disintegrating tablet
Cetirizine (Zyrtec)
Cough suppressant medications act …..
On the central nervous system to suppress the urge to cough
Expectorants

Ibuprofen (Advil, Motrin)
Naproxen (Aleve)
Aspirin
Pain and fever reducer, but not commonly recommended due to the risk of bleeding and developing gastric ulcers.
Aspirin isn’t recommended for children due to the risk of a rare but dangerous disease called Reye’s syndrome.
Reye’s syndrome
An acute condition that causes swelling in the brain (encephalopathy) and liver (hepatitis).
Other Treatments for cold symptoms are:
Plenty of fluids to help treat the side effects of cold medications and loosen mucus
Rest until symptoms resolve and the cold virus runs its course (five to seven days)
Vitamin C and zinc to boost the immune system and help prevent frequent cold infections.
Eucalyptus and other herbal medications to help relieve cold symptoms
Influenza (Flu)
Viral infection (doesn’t respond to antibiotics)
Can cause life threatening complications.
More severe symptoms than the cold (fever, dehydration)
Can lead to pneumonia and hospitalization
Who should receive seasonal flu vaccine?
The elderly
Children
Pregnant women
People with chronic diseases
People with compromised immune systems
Healthy adults living with high-risk people
Healthy adults caring for high-risk people
Antiviral as flu treatment…
Can shorten the length of an illness or reduce the severity of the symptoms.
Antivirals must be taken within 36 to 48 hours of the start of symptoms
Examples of antiviral medication:
Oseltamivir (Tamiflu)
Zanamivir (Relenza) inhaler
Beta-2 receptor agonists
(meaning these medications enhance the effect of beta-2 receptors) act similarly in the lungs to cause smooth muscle relaxation. There are two kinds of beta-agonist inhalers- short acting and long acting.
Short-acting beta-agonist inhalers are used to
provide quick relief.
Some examples of short-acting inhalers are:
Albuterol HFA
Levalbuterol (Xopenex)
Pirbuterol (Maxair)
epinephrine
adrenaline
Example of epineephrine use:

People who are allergic to such things as nuts, bee stings, or latex will often carry an epinephrine auto-injector for emergency situations.
Long-acting beta-agonist inhalers
Have a slower onset of action, but provide relief for a longer period and are used as maintenance therapy in combination with steroid inhalers.
Steroid medications simply produce an anti-inflammatory effect in the lungs.
examples of long-acting inhalers are:
First drug listed in the combination of inhalers is the long-acting beta agonist and the second drug is the steroid.
Salmeterol/fluticasone (Advair)
Formoterol/budesonide (Symbicort)
Vilanterol/ fluticasone(BREO Ellipta)
Anticholinergic medications
Used to prevent constriction of the smooth muscle surrounding airways. These medications are mainly used as a long-term therapy of COPD, but ipratropium may also be used to treat immediate relief of asthma symptoms. These medications are also available as inhalers.
Examples of anticholinergic medications are:
Ipratropium bromide (Atrovent)
Tiotropium (Spiriva)
Side effects of these medications are dry mouth, nausea, and a metallic taste in the mouth.
Corticosteroid medications
Used as maintenance therapy to reduce airway obstruction by decreasing inflammation.
It takes 2-3 weeks for these medications to exert some effect, and it may take from 6-8 weeks for maximum symptom relief.
Examples of steroid inhalers are:
Budesonide (Pulmicort)
Fluticasone (Flovent)
Mometasone (Asmanex)
Side effects of the steroid inhalers include a sore throat, a bad taste in the mouth, and thrush (a fungal infection).
Some examples of oral/injectable corticosteroids are:
Prednisone (Deltasone)
Prednisolone (OMNIPRED)
Dexamethasone (Maxidex)
Methylprednisolone (Medrol)
Leukotriene modifiers
Work by producing bronchodilation to improve allergy or asthma symptoms.
Examples of leukotriene modifiers are:
Montelukast (Singulair)
Zafirlukast (Accolate)
Bronchitis
Is the acute or chronic inflammation and/or infection of the mucus membranes of the bronchial passages of the respiratory tract. The main symptom of acute bronchitis is a cough lasting more than 5-7 days.
Bronchitis treatments
Treatment is targeted for symptom relief. On the other hand, chronic bronchitis patients with a productive cough that persists for several months may need further evaluation to possibly diagnose asthma or COPD.
Patients commonly use acetaminophen, ibuprofen, and naproxen to treat pain and reduce inflammation. Patients can use guaifenesin and dextromethorphan to relieve coughing.

The endocrine system is composed of
- thyroid glands
- parathyroid glands
- pituitary glands
- adrenal glands
- pancreas
- gonads
- pineal glands.
What is the main function of the endocrine glands?
To produce hormones.
Hormone comes from the Greek word meaning :
“impulse” or “to urge on”.
the hormone prolactin “urges” the….
mammary glands to secrete milk
insulin “urges” blood cells to..
Take on glucose
The endocrine glands are regulated by two systems:
positive feedback and negative feedback.
Positive Feedback :
System is activated by a stimulus (baby sucking stimulates system to release prolactin stimulating mammary glands)
Negative feedback
Acts like a thermostat. Opposite to the stimulus.
If there’s too much stimulus the gland stops or slows production.
If there’s too little stimulation the gland increases production.
Some hormones are also controlled directly by the
Nervous system

Symptoms of Hyperthyroidsm (Graves’ disease)
- Tremors or shakiness
- Palpitations
- Weakness
- Weight loss
- Insomnia
- Increased heart rate
- Sweating
- Protrusion of the eyeballs
Treatment for Hyperthyroidsm/ Grave’s disease
Radioactive iodine is a commonly used treatment for hyperthyroidism. Thyroid cells are the only cells that absorb iodine, so there’s no ill effect of the radioactive iodine on other cells of the body.
Once thyroid cells absorb radioactive iodine, they’re either damaged or killed. The body then eliminates the iodine by excretion.
Surgical removal of the enlarged gland with or without iodine is another treatment option for hyperthyroidism.
The surgery is called thyroidectomy.
Patients often require thyroid replacement therapy after surgery.
Medications to treat hyperthyroidism include:
Methimazole (Tapazole)
Propulthiouracil (PTU)
Hypothyroidism
disorder that causes the release of too little thyroid hormone. Underproduction of thyroxine or thyroid hormone slows down the body’s metabolism. Hypothyroidism will often cause an increased level of TSH due to a low level of thyroid hormone in the blood. (Remember the negative feedback system). Hypothyroidism is a chronic disease that occurs more commonly in women.
Symptoms of Hypothyroidism
- Mental and physical sluggishness
- Obesity
- Enlargement of the tongue
- Swelling of the lips and nose
- Sensitivity to cold
- Muscle weakness
Treatment for hypthyroidism is
Thyroid hromone replacement
- Levothyroxine (Levoxyl, Sythroid, Levothroid)
- Thyroid (Armour Thyroid)
Goiter
Disease characterized by enlargement of the thyroid gland, causing swelling of the neck.
A goiter can be caused by either hypothyroidism or hyperthyroidism.
Most patients with a goiter are asymptomatic with the exception of airway obstruction, difficulty swallowing, and a hoarse voice due to the enlarged gland.
Treatment goiter
Surgical removal- the patient will need thyroid replacement therapy after surgery- and radioactive iodine.
Cushing’s Syndrome
Adrenal gland disorder caused by a hyperactive adrenal gland. In most cases hyperactivity is the result of too much ACTH secretion by the pituitary gland.
Cushing’s Syndrome Symptoms
Weight gain
Susceptibility to bruises
Hypertension
Diabetes
Weakness
Treatment of Cushing’s Syndrome
Mitotane (Lysodren)
Cyproheptadine (Periactin)
Ketoconazole (Nizoral)
Surgical removal of tumor of the pituitary or adrenal gland
Addison’s disease
Is due to abnormally low levels of hormones secreted by the adrenal glands. This disease may result from steroid abuse or from an autoimmune disease.
Symptoms of Addison’s disease

Weight loss
Hypoglycemia (low blood sugar)
Muscle weakness and pain
Hypotension
Treatment of Addison’s Disease
Replacement of adrenal hormones.
- Hydrocortisone (Solu-Cortef)

Diabetes
Deficiency or decreased production of insulin by the pancreas.
Three types of diabetes:
Type 1, Type 2, and gestational diabetes.
Normal fasting blood sugar level in healthy individuals should be less than?
100 milligrams per deciliter.
A test that measures average blood sugar levels over a two-to- three month period is called?
Hemoglobin A1C
A normal A1C level for healthy individuals is 4 to 6.2 percent.
Symptoms of Diabetes include:
- Feeling very thirsty all the time
- Frequent urination
- Extreme fatigue or tiredness
- Weight loss
- Blurred vision
- Tingling pain or numbness in hands or feet
- Cuts or bruises that are slow to heal
Type 1 Diabetes
Average time of onset is childhood, specifically 10 years of age or earlier
Sudden onset
Mainly caused by the destruction of insulin-producing cells of the pancreas due to genetic or environmental factors
Accounts for less than 10 percent of all diabetes
Type 2 Diabetes
Average time of onset in adulthood
Progressive disease
Mainly caused by decreased insulin secretion or development of insulin resistance
Accounts for more than 90 percent of all diabetes
Gestational Diabetes
Occurs during pregnancy
If uncontrolled or untreated, may cause birth defects
Some of the major complications of uncontrolled diabetes are:
Heart disease
Hypertension
Stroke
Nerve damage (diabetic neuropathy)
Blindness (diabetic retinopathy)
Foot ulcers or wounds that don’t heal
Infections of resistant organisms
Amputations (removal of part of a limb)
Kidney failure
Lifestyle modifications that can prevent diabetes and avoid chronic complications of the disease:
Balanced diet
Decreased consumption of sugars
Exercise
Maintaining healthy weight
Treatment of type 1 diabetes ?
Insulin injections
Treatment of type 2 diabetes?
Oral medications
Insulin injections
(also in combination)
Metformin
- first line of treatment for type 2 diabetes after lifestyle modifications fail
Metformin works by increasing glucose uptake in muscles and inhibiting glucose release from the liver.
It also increases our body’s sensitivity to insulin.
Metformin causes side effects in the kidney’s, so it generally isn’t the drug of choice for patients with poor kidney function. Metformin doesn’t cause hypoglycemia, contrary to most other oral diabetes medications.
Insulin
Primary treatment option for type 1 diabetes.
Insulin is administered via the subcutaneous route (injection under the skin).
Insulin can cause severe hypoglycemia, so regular monitoring of blood glucose levels while taking insulin is highly important. Insulin is available in short-acting, intermediate-acting, and long-acting forms.
Important Insulin facts:
Insulin must be stored in a refrigerator
Insulins are administered via injection under the skin or into the veins.
Once opened or removed from the refrigerator, an insulin vial is only good for 28 days at room temperature
Only administer insulin via an insulin needle.
Insulin is measured in units, not mgs or ml (for ex: 40 units)
Short-Acting Insulin
Work immediately (5-30 minutes)
Typically used with meals to control increased glucose level with food
Examples: Humulin R, Novolin R, Humalog, Novolog
Intermediate-Acting Insulin
Work within 2-4 hours
Typically used to control glucose levels throughout the day between meals
Examples: Humulin N, Novolin N, Humalog 70/30
Long-Acting Insulin
Work within 6-10 hours
Typically used to control glucose levels throughout the day between meals
Examples: Lantus, Levemir
Hypoglycemia
Hypoglycemia is defined as dangerously low levels of blood glucose.
Symptoms of Hypoglycemia
