A blood cell (also called blood corpuscle) is any cell of any type normally found in blood. Blood is a specialized Bodily fluid that delivers necessary substances to the body's cells €”such as nutrients and oxygen—and transports Waste products In mammals, these fall into three general categories:
Together, these three kinds of blood cells sum up for a total 45% of blood tissue (55% is plasma). Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands Red blood cells are the most common type of Blood cell and the Vertebrate body's principal means of delivering Oxygen to the body tissues via the Blood Platelets, or Thrombocytes, are small cytoplasmic bodies derived from cells They circulate in the Blood of Mammals and are involved Blood plasma is the Liquid component of Blood, in which the Blood cells are suspended [1]
| cell type | Primary function | Lifetime |
|---|---|---|
| Red blood cells | transport of oxygen | 120 days |
| White blood cells | produces antibodies to fight infection | days to years |
| Platelets | blood clotting | 8 days |

A decrease in number of blood cells is called cytopenia. A cell type is a distinct morphological or functional form of cell. Red blood cells are the most common type of Blood cell and the Vertebrate body's principal means of delivering Oxygen to the body tissues via the Blood Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the Antibodies (also known as immunoglobulins, abbreviated Ig) are Gamma globulin Proteins that are found in Blood or other Bodily Platelets, or Thrombocytes, are small cytoplasmic bodies derived from cells They circulate in the Blood of Mammals and are involved Hematology ( American English) or haematology ( British English) is the branch of biology (physiology Pathology, Clinical laboratory Cytopenia is a reduction in the number of Blood cells It takes a number of forms Low Red blood cell count Anemia. An increase, on the other hand, is called polycythemia. Polycythemia (or polycythaemia or erythrocytosis) is a condition in which there is a net increase in the total number of Blood cells, primarily Red [2]
