Use the graph to the right. At rest, the PO2 in the lungs is 104 mmHg. In the tissues, the PO2 is 40 mmHg. a) Number the hatchmarks on the y-axis for the % O2 released from Hb. (e.g. if Hb is 75% saturated, what % of O2 has been released to the tissues?) b) What is the % saturation of hemoglobin in the blood in the pulmonary veins (fully oxygenated blood!)? c) What is the % saturation of hemoglobin in the blood when in skeletal muscle? d) What % of oxygen is released from hemoglobin when in skeletal muscle? e) Where does the oxygen go when the hemoglobin becomes less saturated? 100 90 80 70 Hemoglobin saturation, % 60 50 40 30 20 10 0 20 40 60 Resting cell 80 100 Alveoli PO2 (mm Hg)
Under resting conditions ________ is the partial pressure of O2 in the blood leaving the left ventricle, and ________ is the partial pressure of CO2 in the blood leaving the left ventricle.
