Question

Emphysema is a disease characterized by a great reduction in the number of functioning alveoli in the lungs. What effect would emphysema likely have on the respiratory system? a. Less gas exchange would occur with the blood. b. Less air could travel through the trachea. c. Air could no longer pass through the nasal cavity. d. Air could no longer vibrate the vocal cords of the larynx.

Step 1

Alveoli are small sacs at the end of the bronchioles in the lungs that are covered in capillaries. Their main function is to exchange gases between the lungs and the blood. They take in oxygen from the air we breathe in and release carbon dioxide from the blood to Show more…

Key Concepts

Emphysema

Emphysema is a chronic respiratory disease characterized by the destruction of alveolar walls, leading to a decrease in the number and integrity of alveoli. This results in reduced respiratory efficiency and diminished overall lung compliance.

Alveoli

Alveoli are the microscopic air sacs in the lungs where gas exchange occurs. They provide a large surface area that facilitates the transfer of oxygen into the blood and the removal of carbon dioxide from it.

Gas Exchange

Gas exchange is the process by which oxygen is absorbed into the bloodstream and carbon dioxide is expelled. A reduction in the number of functioning alveoli, as seen in emphysema, leads to a compromised gas exchange process, reducing the efficiency of oxygen uptake and carbon dioxide elimination.
