A mature red blood cell (RBC). Each is a nonnucleated, biconcave disk averaging 7.7 /am in diameter. An RBC has a typical cell membrane and an internal stroma, or framework, made of lipids and proteins to which more than 200 million molecules of hemoglobin are attached. Hemoglobin is a conjugated protein consisting of a colored iron-containing portion (hematin) and a simple protein (globin). It combines readily with oxygen to form an unstable compound (oxyhemoglobin). The total surface area of the RBCs of an average adult is 3820 sq m, or about 2000 times more than the external total body surface area.
