A blood cell is any cell of any type normally found in blood. In mammals, these fall into three general categories:
* Red blood cell, whose main purpose is the transport of oxygen;
* White blood cell, which produces antibodies to fight infection;
* Platelet, which is actually a fragment of the large bone marrow cells known as megakaryocytes and are important in blood clotting.
Together, these three kinds of blood cells sum up for a total 45% of blood tissue (55% is plasma).

The three types of blood cells are :-
1)red blood cells or erythrocytes- help in transfer of respiratory gases.
2)white blood cells or leukocytes- helps in destroying any foreign material entering the body.
3)blood platelets or thrombocytes-it help in coagulation of blood when injured.

Red blood cells are cells that contain hemoglobin and carries oxygen to the tissues.
White blood cells are cells that fight infection.
Platelets heal your wounds by clotting blood.

platelets for coagulation
red for transporting oxygen and other nutrients to cells throughout the body
white for immunity / fighting disease
*****************************************
"Blood is a liquid tissue. Suspended in the watery plasma are seven types of cells and cell fragments.
* red blood cells (RBCs) or erythrocytes
* platelets or thrombocytes
* five kinds of white blood cells (WBCs) or leukocytes
o Three kinds of granulocytes
+ neutrophils
+ eosinophils
+ basophils
o Two kinds of leukocytes without granules in their cytoplasm
+ lymphocytes
+ monocytes"
