Assume the po2 in a resting tissue is 40 mmhg. how much of the total o2 bound to hemoglobin in arterial blood will be released as the blood moves through the tissue capillary beds? assume that the %hb saturation is 99% in arterial blood. hemoglobin saturation, % 40 60 80 resting cell po, (mm hg) 100 alveoli
a) about 25%
b) about 60 mmhg
c) about 75%
