Question

Quizplus · Accepted Answer

Hemoglobin that is 100% saturated with oxygen is found in the alveoli of the lungs. This is where oxygen from the air is exchanged with carbon dioxide from the blood, and where hemoglobin picks up oxygen to transport it to the body's tissues. While hemoglobin may be partially saturated with oxygen in other structures, such as the capillaries of active muscles, it is only 100% saturated in the alveoli. The hepatocytes of the liver and cells of the intestinal tract do not play a direct role in oxygen transport and therefore do not contain hemoglobin.
