Question

why is the amount of gas exchange is smaller in a damaged air sac?

Answer 1

Answer:

Emphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung. ... As you breathe in air, the alveoli stretch, drawing oxygen in and transporting it to the blood. When you exhale, the alveoli shrink, forcing carbon dioxide out of the body.

Answer 2

The amount of gas exchange is smaller in a damaged air sac because the surface area is lower in the damaged air sac.

Gaseous exchange:

• Gas exchange is the biological process through which gases enter or exit the bloodstream across cell membranes.
• Gas exchange occurs constantly between the blood and the cells throughout the body, as well as between the blood and the air inside the lungs.
• The movement of oxygen and carbon dioxide between the lungs and blood is referred to as the gaseous exchange.
• We can breathe because of our lungs and respiratory system.
• They transport oxygen into our bodies (this is known as inspiration or inhalation) and expel carbon dioxide (called expiration, or exhalation).
• Respiration is the exchange of oxygen and carbon dioxide.
