The partial pressure gradient of oxygen determines the direction of the movement of this respiratory gas. True or False

True - The partial pressure gradient of oxygen determines the direction of the movement of this respiratory gas

Explanation:

The two gases involved in respiration are Oxygen and Carbon dioxide.

The movement of Oxygen and carbon dioxide is usually influenced by their partial pressure differences.

In the circulatory system, the main exchanges takes place at the Arterial end of the pulmonary capillaries. The Oxygen diffuses from the alveoli into the blood and the Carbon dioxide diffuses from the blood into the alveoli. The oxygen is needed by the cells and the blood helps in transporting it to cells. However the Carbon dioxide is toxic to the cells hence its diffusion to the alveoli of the lungs for expulsion out of the body system.
