Question

Quizplus · Accepted Answer

Hemoglobin contains iron, which is essential for oxygen transport. RBCs pick up oxygen in the lungs' pulmonary capillaries. The shape of an RBC is biconcave, not like a deflated soccer ball. Hemoglobin without oxygen is called deoxyhemoglobin, not debonded hemoglobin. The lifespan of an RBC is about 120 days, not 60.
