eritrosite

Eritrosite is the scientific term for a red blood cell. These are the most common type of blood cell and are responsible for transporting oxygen from the lungs to the body's tissues and then carrying carbon dioxide back to the lungs to be exhaled. Eritrosites are produced in the bone marrow through a process called erythropoiesis. Mature eritrosites lack a nucleus and most organelles, which maximizes the space available for hemoglobin, the protein that binds to oxygen. The characteristic red color of blood is due to hemoglobin. The typical lifespan of an eritrosite is about 120 days, after which they are removed from circulation by the spleen and liver. Anemia is a condition characterized by a deficiency in red blood cells or hemoglobin, leading to reduced oxygen transport. Conversely, polycythemia refers to an excess of red blood cells. The number of eritrosites in the blood is a key indicator in medical diagnostics.
