Why will the ph balance of a body with a damaged lower respiratory system change?
a. the lungs may not remove as much carbon dioxide as before the damage.
b. the epithelial cells may not remove as many foreign particles as before the damage.
c. the lungs may not take in as much oxygen as before the damage.
d. the epithelial cells may not keep the inside of the lungs as lubricated as before the damage.

Option A

Explanation: The lungs in the body of the of the organism helps in maintaining the pH balance of the body.

The lungs and kidneys of the body helps in controlling the pH of the body. The normal pH of the body is maintained by the pH of the blood which is 7.4.

The disruption in the acid base balance of the body can place in the either direction. This disruption can be considered as medical condition known as acidosis and alkalosis.

This can be because damaged lungs might not be enough sufficient to remove carbon dioxide out of the body which changes the pH of the blood.

i believe the answer would be 'd'.

hope this !
