Question 2
When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. The carbonic acid causes the pH to become more acidic. When the blood pH becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood pH. Which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis in the blood pH?(1 point)

Answer 1

For Question 1, the stimulus directly causing the reaction (removal of excess water) is:

Blood Volume increases.

For Question 2, the response by the body that would eliminate the excess carbon dioxide and help maintain homeostasis in blood pH is:

Breathing more deeply and frequently.
