What Do Red Blood Cells Do? Red blood cells carry oxygen and nutrients to the tissues in the physique and take away carbon dioxide. They're also referred to as erythrocytes. They get their red colour from a pigment known as hemoglobin, and it is the hemoglobin that truly carries the oxygen and carbon dioxide. Red blood cells are made in the bone marrow. A crimson blood cell begins as a spherical cell with a round nucleus, and as this cell grows inside the bone marrow, it picks up hemoglobin. Finally, when the purple blood cell is mature, it sheds the nucleus, leaves the marrow and enters the bloodstream. The lack of a nucleus is one thing that makes a red blood cell totally different from different mature cells. It has an indented middle and is ready to deform itself sufficient to squeeze through capillaries. A purple blood cell is lively for about 4 months. After this time, it leaves the circulatory system and the body destroys it within the spleen, liver, bone marrow and blood vessels. To change these destroyed cells, the body has to create about two million purple blood cells each second. Every cubic millimeter of a man’s blood accommodates about 5.2 million pink blood cells. The corresponding count for women is about 4.6 million.
