e. option a is the answer- the oxygen-rich blood contains 20 ml of oxygen in 100 ml of total blood volume. Of that 20 ml, only 0.3 ml dissolved in the plasma. the remaining 19.7 ml of oxygen is still in the blood, but it's bound to hemoglobin
e. option b is the answer
in alveoli: 100 PO2a&d 97 percent saturation of hemoglobin
in resting cell, PO2 is 40, 73 percent saturation of hemoglobin
23 percent change in saturation of hemoglobin
(97----> 73)
• Fully saturated blood holds ~ 200 ml of O2/ liter, so:
200 ml X .23 =46 ml O2 has been released into the tissues!
*Reserve is built in to dump O2 when metabolic activity increases
f. the option is - If tissues wereive and tissue pO2 drops to 30 mmHg, Hemoglobin saturation falls from 97% to 57% soi.e. 40 % t change
200 mL (.40)= 80 mL o2 delivered to tissues
