1. What is the primary function of the respiratory system?
To exchange oxygen and carbon dioxide between the body and the environment.
2. What are the major organs of the respiratory system?
Nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli.
3. What is the function of the alveoli?
They are the sites of gas exchange in the lungs.
4. What type of epithelium lines most of the respiratory tract?
Pseudostratified ciliated columnar epithelium.
5. What is pulmonary ventilation?
The movement of air into and out of the lungs.
6. What muscle is primarily responsible for inspiration?
The diaphragm.
7. What happens to intrapulmonary pressure during inspiration?
It decreases below atmospheric pressure.
8. What happens during expiration?
Air leaves the lungs as pressure increases.
9. What is external respiration?
Gas exchange between the lungs and blood.
10. What is internal respiration?
Gas exchange between blood and body tissues.
, 11. Which gas is transported mainly by hemoglobin?
Oxygen.
12. In what form is most carbon dioxide transported in the blood?
As bicarbonate ions.
13. What is the function of surfactant?
It reduces surface tension in the alveoli.
14. Which cells produce surfactant?
Type II alveolar cells.
15. What is tidal volume?
The amount of air inhaled or exhaled during normal breathing.
16. What is vital capacity?
The maximum amount of air that can be exhaled after a maximum inhalation.
17. What is residual volume?
The amount of air remaining in the lungs after forced expiration.
18. What structure prevents food from entering the trachea?
The epiglottis.
19. What is the function of the pleura?
To reduce friction and help lungs expand.
20. What is hypoxia?
A deficiency of oxygen in body tissues.
21. What is hyperventilation?
Rapid breathing that decreases carbon dioxide levels.
22. What is the role of the medulla oblongata in respiration?
It controls the basic rhythm of breathing.
