Question

A blood vessel in the liver has blood with pO2 of 45mm Hg which is much higher than the pO2 of the tissues in the liver. Does the O2 diffuse into the blood from the tissues or diffuse from the blood into the tissues

Answer 1

Explanation:

The total pressure of gas in the alveolar space is 100 mm Hg the partial pressure of co2 is 45 mm Hg What is the maximum partial pressure of oxygen.

PH2O is the partial pressure of water equal to approximately 45 mm Hg. FiO2 is the fraction of inspired oxygen. PaCO2 is the carbon dioxide partial pressure in alveoli, which in normal physiological conditions is approximately 40 to 45 mm Hg, and the RQ (respiratory quotient).
