respiratory terms

Question 1

consists of the lungs and air passages. This system is responsible for taking on oxygen, a gas needed by all body cells and removing carbon dioxide, a gas that is metabolic waste product produced by the cells

Answer 1

respiratory system

Question 2

has two openings, called nostrils or nares, through which air enters

Answer 2

nose

Question 3

a wall of cartilage, that divides the nose into two hollow spaces

Answer 3

nasal septum

Question 4

tiny, hair like structures that help move the mucous layer that lines the airways pushing trapped particles toward the esophagus, where they can be swallowed. The olfactory receptors for the sense of smell are also located in the nose

Answer 4

cilia

Question 5

cavities in the skull that surround the nasal area. They are connected to the nasal cavity by short ducts. The sinuses are lined with a mucous membrane, which warms and moistens air. The sinuses also provide resonance for the voice.

Answer 5

sinuses

Question 6

or throat lies directly behind the nasal cavities. As the air leaves the nose, it enters the pharynx is divided into three sections. The nasopharynx. The pharynx is divided into three sections.

Answer 6

pharynx

Question 7

voice box, lies between the pharynx and trachea. It has nine layers of cartilage, contains 2 folds called vocal cords,

Answer 7

larynx

Question 8

a special leaf like peice of cartilage closes the opening into the larynx during swallowing. This prevents food and liquids from entering the respiratory tract

Answer 8

epiglottis

Question 9

( windpipe) is a tube extending from the larynx to the center of the chest

Answer 9

trachea

Question 10

the trachea divides into two bronchi near the center of the chest, a right bronchus and left bronchus. The right is shorter, wider and extends more vertically than the left

Answer 10

branchi

Question 11

smallest branches of the bronchus, the smallest bronchioles, called terminal bronchioles, end in air sacs, called aveoli

Answer 11

bronchioles

Question 12

resemble a bunch of grapes. The adult lung contains approximately 500 million alveoli. They are made up of one layer of squamous epithelial tissue and contain a rich network of blood capillaries

Answer 12

atveoli

Question 13

the bronchi and alveoli are found in the lungs. The right lung has 3 sections or lobes, the superior, middle and the inferior. The left lung has only two lobes. The superior and inferior. The left lung is smaller because the heart is located towards the left side of the chest.

Answer 13

lungs

Question 14

is the process of breathing. Involves two phases’ inspiration and expiration.

Answer 14

ventilation

Question 15

inhalation is the process of breathing in air. The diaphragm9dome-shaped) muscle between the thoracic and abdominal cavities and the intercostal muscles contract and enlarge the thoracic cavity to create a vacuum

Answer 15

inspiration

Question 16

air rushes in through the airways to the alveoli, where the exchange of gases takes place.

Answer 16

respiration

Question 17

when the diaphragm and intercostal muscles relax. air is forced out of the lungs and air passages the process of respiration is controlled by the respiratory center in the medulla oblongata of the brain

Answer 17

expiration

Question 18

the exchange of oxygen and carbon dioxide between the lungs, and bloodstream. Oxygen breathed in through the respiratory system, enters the alveoli

Answer 18

external prespiration

Question 19

is the exchange of carbon dioxide and oxygen between the tissue cells and the bloodstream. Oxygen is carried to the tissue cells by the blood

Answer 19

internal respiration

Question 20

the cells use the oxygen and nutrients to produce energy, water, and carbon dioxide

Answer 20

cellular respiration

Question 21

a chronic inflammatory disorder of the airways, usually caused by a sensitivity to an allergen such as dust, pollen, an animal, medications or food. Stress, Overexertion, and infection can also cause an asthma attack, during which bronchospasms narrow the openings of the bronchioles, mucus production increases and edema develops in the mucous lining

Answer 21

Asthma

Question 22

an inflammation of the bronchi and bronchial tubes, Acute bronchitis is very common and frequently develops from a cold or the flu. Caused by a viral infection. Symptoms include productive cough, dyspnea, rales, chest pain, and fever. Treatments include expectorants, non steroidal anti inflammatory drugs; decongestants cough suppressants, rest , and drinking large amounts of water

Answer 22

bronchitis

Question 23

COPD is a term used to describe any chronic lung disease that results in obstruction of the airways and limitations of air flow. Chronic asthma, chronic bronchitis, emphysema and tuberculosis lead to COPD. Smoking is the primary cause but allergies and chronic respiratory infections are also factors shortness of breathe, wheezing, chest tightness, chronic cough, and physical impairment, Treatment is cough medications, bronchodilators, oxygen, and pulmonary rehabilitation to optimize respiratory function

Answer 23

chronic obstruction pulmonary disease

Question 24

a noninfectious, chronic respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity, resulting in an abnormal and permanent enlargement of the airspace’s. Most common cause is heavy smoking and prolonged exposure to air pollutants. Symptoms include dyspnea, a felling of suffocation, pain, barrel chest, and chronic cough, and cyanosis, rapid respiration accompanied by prolonged expiration and eventual respiratory failure and death. There is no cure, treatment methods include bronchodilators inhaled, steroids, breathing exercises, prompt treatment of respiratory infections, oxygen therapy, respiratory therapy and avoidance of smoking

Answer 24

emphysema

Question 25

a nosebleed occurs when capillaries in the nose become congested and bleed. Can be caused by injury or blow to the nose, hypertension, chronic infection, anticoagulant drugs, nose picking, dry or cold air, blood diseases such as hemophilia and leukemia, compressing the nostrils toward the septum, elevating the head and titling it slight forward with applying cold compress

Answer 25

epistaxis

Question 26

is a highly contagious viral infection of the upper respiratory system. Onset is sudden, and symptoms include chills, fever. a cough, sore throat, runny nose, muscle pain, and fatigue. Treatment methods include bed rest, fluids, analgesics, antipyretics ( for fever) antiviral meds, should be started with onset of symptoms

Answer 26

Question 31

a condition in which an individual stops breathing while asleep, causing a measurable decrease in blood oxygen levels. Two main types: obstructive sleep apnea which is caused by a blockage in the airway that occurs when the muscles that keep the airway open relax and allow the tongue and palate to block the airway. Central sleep apnea is caused by a blockage in the air passage that occurs when the muscles that keep the airway open relax and allow the tongue and palate to block the airway. This condition is more common in men. factors that can because this is obesity, hypertension, smoking, alcohol ingestion, and or the use of sedatives may increase the severity.
