The Process by Which Dissolved Gases are Exchanged Between the Cells

Question

The process by which dissolved gases are exchanged between the cells and interstitial fluids is
A) pulmonary ventilation.
B) external respiration.
C) internal respiration.
D) cellular respiration.
E) breathing.

Accepted Answer

Internal respiration is the process by which gases, such as oxygen and carbon dioxide, are exchanged between the cells and interstitial fluids. This occurs as a result of cellular respiration, where cells use oxygen to generate ATP and produce carbon dioxide as a waste product. Pulmonary ventilation and breathing refer to the movement of air in and out of the lungs, while external respiration refers to the exchange of gases between the air in the lungs and the blood.
