Red blood cells, referred to as erythrocytes in academia and medical publishing, also known as red cells, erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebra
There is an immense size variation in vertebrate red blood cells, as well as a correlation between cell and nucleus size. Mammalian red blood cells, which do not contain nuclei, are considerably smaller than those of most other vertebrates.
Mature red blood cells of birds have a nucleus, however in the blood of adult females of penguin Pygoscelis papua enucleated red blood cells (B) have been observed, but with very low frequency.
Scanning electron micrograph of blood cells. From left to right: human red blood cell, thrombocyte (platelet), leukocyte.
Two drops of blood are shown with a bright red oxygenated drop on the left and a darker red deoxygenated drop on the right.
A blood cell is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells, white blood cells, and platelets. Together, these three kinds o

Diagram showing the development of different blood cells from hematopoietic stem cells to mature cells.
The darker red blood syringes have deoxygenated blood, whereas the brighter red have oxygenated blood.
