Why is the amount of gas exchanged in a damaged air sac less?

Answer 1

When an air sac is damaged, the surface area available for gas exchange is reduced. Gas exchange occurs across a membrane, and if this membrane is compromised, the efficiency of gas exchange is decreased. Additionally, damage to the air sac can disrupt the diffusion gradient necessary for gas exchange, further limiting the amount of gas exchanged. Overall, a damaged air sac impairs the ability of the respiratory system to effectively exchange gases, leading to a decrease in the amount of gas exchanged.

Answer 2

Damage to air sacs can reduce the surface area available for gas exchange, impair the thinness of the membrane needed for diffusion, or disrupt the flow of air through the respiratory system. These factors can limit the efficiency of gas exchange, resulting in a decreased amount of gas exchanged.

Answer 3

because the carbon dioxide is not able to presuer and overpower the oxygen as so it is not able to do so

Answer 4

The damage reduces the amount of surface area in the sac which reduces the amount of air that can be exchanged. This is why the amount of gas/air exchange is smaller.

Answer 5

The alveolar sacs must adhere closely in order for gas exchange to occur. In emphysema the air sacs are dilated causing less carbon dioxide to escape.

Answer 6

Damaged air sacs have a lower amount of air surface. This reduces the amount of gas exchanged because the larger the surface the larger the amount.
