1. What gas is produced by normal metabolic activities and must be removed from a person\'s circulatory systemto keep the blood and body tissue between pH between 7.35-7.45? ANS: . This gas is exchanged between the tissues and the blood of the circulatory system in two locations of the body:

a. This same gas is produced by cells of the body goes down its pressure gradient and enters the circulatory system during ________ gas exchange and is transported to the lungs.

b. This same gas is removed from the body at the lungs by going down its pressure gradient during ________ gas exchange and is eventually exhaled.

Solution

Carbon dioxide (CO₂) is produced as a result of metabolic activities and needs removal from circulatory system to maintain pH of body fluids between 7.35-7.45.

CO₂ is exchanged between the tissues and blood of the circulatory system in two locations:

a. Capillary gas exchange for transportation to the lungs.

b. Alveolar gas exchange for exhalation.

Overall, these processes maintains homeostasis by taking oxygen and removing carbon dioxide, thereby maintaining respiration.
