Study Notes
Carbon Dioxide and Blood
- Most of the carbon dioxide enters the blood in the tissue capillaries.
Factors Affecting Carbon Dioxide Movement
- The critical factor that determines carbon dioxide movement in or out of the blood is the partial pressure of carbon dioxide (pCO2).
Acid-Base Balance
- The major determinant of the acid–base balance of the body is the pH level, which is largely determined by the buffering system that regulates pCO2.
Carbon Dioxide Movement
- The factor that determines carbon dioxide movement in or out of the blood is the partial pressure gradient of carbon dioxide between the blood and the surrounding tissues or air.
Pulmonary Circulation
- The filling of the pulmonary capillaries with blood is called pulmonary perfusion.
