An erythrocyte is more commonly known as a red blood cell, which is the most numerous type of blood cell Erythrocytes contain the red pigment hemoglobin and are responsible for oxygen transport In humans, the number of erythrocytes in the blood varies between 4 5 and 5 5 million per cubic millimeter They survive for about four months and are then destroyed in the spleen and liver
or red blood cell or red blood corpuscle Blood cell that carries oxygen from the lungs to the body tissues. Hemoglobin gives the cell and whole blood its colour. Red cells are small, round, flexible, and concave on both sides and lack a nucleus. They develop continuously in bone marrow in several stages and are stored in the spleen. The mature form lives 100-120 days. Adult human blood has about 5.2 million red cells per cu mm. Some conditions change their shape (e.g., pernicious anemia, sickle-cell anemia) or number (e.g., anemia, polycythemia)
(red blood cell, BC) - a very small circular biconcave cell produced in the bone marrow and found in the blood stream; contains hemoglobin, which carries oxygen to body tissues
