One of the factors that affect breathing rate and depth is the partial pressure of gases. Gases passively diffuse across plasma membranes. Indicate the flow of gases in these scenarios. 1. The partial pressure of oxygen within alveoli is 100mmHg while the partial pressure of oxygen in the adjacent pulmonary capillary is 80mmHg. Which way will oxygen diffuse in this scenario? 2. The partial pressure of carbon dioxide in a body cell is 45mmHg while the partial pressure of carbon dioxide in the adjacent systemic capillary is 25mmHg. Which way will carbon dioxide diffuse in this scenario?
