Red blood cell, also called erythrocyte, cellular component of blood cell which in the circulation of vertebrates gives its characteristic colour and carry oxygen from the lungs to the tissues.
The red blood cell develops in bone marrow in several stages: from a hemocytoblast it becomes an erythroblast (normoblast), during two to five days of development, the erythroblast gradually fills with hemoglobin, and its nucleus and mitochondria disappear. In a late stage the cell is called a reticulocyte, which ultimately becomes a fully mature red cell. The average red cell in humans lives 100–120 days; there are some 5.2 million red cells per cubic millimetre in the adult human. Abnormal shape of red blood cells leads to some diseases like oval in pernicious anemia, crescent-shaped in sickle cell anemia, and with projections giving a thorny appearance in the hereditary disorder acanthocytosis. Blood or red cell loss that occurs suddenly or over time and conditions that decrease red blood cell production in the bone marrow will result in a low RBC count leads to anemia.
