Patho Test 2 Flashcards
Upper respiratory system contains
Respiratory endothelium
Pharynx
Larynx
Epiglottis
Lower respiratory system contains
Cilia Trachea Bronchi Bronchiole Alveoli Pulmonary capillaries
Parts of the lung
R/L/ middle…
Right- 3 lobes
Left- 2 lobes
Mediastinum - middle where heart goes
What is Pleura
Double layer casing that goes around the lung
Double blood supply contains
Deoxygenated blood
Oxygenated blood
Deoxygenated blood travels…
From the RIGHT VENTRICLE through PULMONARY ARTERY then to the PULMONARY CAPILLARIES and AVEOLI
Oxygenated blood travels
Through BRONCHIAL ARTERIES then to the LEFT VENTRICLE and then to the BODY
Muscles of respiratory
Diaphragm
Intercostal muscles
Abdominal muscles
Accessory muscles
Which system controls respiration
Autonomic nervous system
Example of voluntary control (respiration)
Singing
Blowing out candles
What is cyanosis
Lack of oxygen
What is a spirometry
Measures volume of air moving in and out of the lungs,
Rate of air flow in and out of lungs
Pulmonary function test is also known as
Spirometry
Upper respiratory diseases
Common cold
Sinus infection
Influence (UPS)
Snoring
Lower respiratory diseases compared to upper respiratory diseases
Are more debilitating, or can be fatal.
Lower respiratory diseases
Influenza (LRS)
Pneumonia
TB
COPD
pneumothorax
Influenza
Viral, acute, highly contagious respiratory infection.
At risk- old, young, immune disorder pts Sx's - fever -cough -fatigue -aches
Can progress to pneumonia
Pneumonia
Bacterial or viral
Acute inflammation of the lungs
Bacterial- treat with antibiotics
Tuberculosis
Contagious
Spread by airborne tubercle bacilli
Primary exposure caused production of antibodies (PPD + Mantoux)
Immediately onset or dormant for awhile
Treated with antibiotics
COPD aka…
Chronic obstructive pulmonary disease
COPD
2 types
Chronic bronchitis
Emphysema
COPD
Inflammation from noxious stimuli in the airway
i.e. Smoke or toxins
Chronic bronchitis
Type of COPD
bronchitis attacks, lasting for several months over a 2 year period.
Swelling of the mucous and mucus production
No cure
Emphysema
Type of COPD
irreversible
Destruction of cilia and mucosa and mucus production closes the airway
Inability to exhale, lung keeps stale air in.
Lung is unable to stretch and take air In.
Effects of emphysema
Pink Puffers
- working hard to get enough O2 and progresses to….
Blue Bloaters
- when tissue become cyanosis because not enough O2 for so long.
Bronchial asthma
Bronchial tubes become inflamed
Treated with steroids (antistamines, bronchodilators)
Severe cases require epinephrine or tracheotomy
Cystic fibrosis
Autosomal recessive
Affects all exocrine glands **
Excessive, viscous mucus secretion causes airway obstruction.
Excessive perspiration can use up electrolytes in the body.
Diagnosis and treatment for cystic fibrosis
Sweat test- to check for elevated levels of salt
Nutritional counseling
Pleurisy
2 types (Dry & pleurisy from effusion)
It’s a complication of other diseases / or trauma
Sharp stabbing pain with inspiration / or cough
Pneumonthorax
Collapse lung
Increase pressure in the cavity allowing the lung to collapse
Weakened area in the lung letting air in the space from inside or from puncture from outside
Atelectasis
Collapse of the lung from rupture of the alveoli forms obstruction, tumor, or pneumothorax
Presents like pneumothorax
Pulmonary embolism
Blockage in one or more arteries in the pulmonary circulation system
Usually from immobility, major surgery, cancer
Lung cancer
Malignant tumor that develops in lung tissue
Many times it’s secondary
Treatment
- surgery, radiation, then chemo
They need to stop smoking
Age related changes
Lung compliance (capacity) decreases
Weakness in muscles of respiration
Postural dysfunction
Lung cancer incidence increases
Joint limitations in rib cage
Cardiac tissue
Pericardium-membrane surrounding the heart
Myocardium- heart muscle forming walls of the chambers , thicker on left = pumps harder
Endocardium- lines myocardium, lining if the chambers
Right VENTRICLE pump to the…
Lungs
Left ventricle pumps to the…
Body
Pumps harder
Structure of the heart
4 chambers
Septum
Valves
arteries of the heart.
Chambers of the heart
Atria (L/R)
Chambers L/R
Right atria receives blood from…
The systemic circulatory through vena cava
R atria is bigger collects more blood
Left atria receives …
Oxygenated blood from the pulmonary veins (4)
Right VENTRICLE pumps blood through….
The pulmonary artery to the lungs
Left ventricle pumps blood through
The aorta to the body and coronary arteries to the heart
Cardiac valves
Atrioventricular valves (AV)
Semilunar valves
