Blood Cells
Three types of cells are found suspended in the plasma of blood. They are: erythrocytes (RBC), leukocytes (WBC) and thrombocytes (Platelets). Erythrocytes (red blood corpuscles) are spherical or oval cells that are responsible for the oxygen carrying capacity of blood. The RBC a..
Blood Groups
The surfaces of erythrocytes contain antigens called Agglutinogens. Two major blood group classifications - ABO grouping system and the Rh system - are based on the presence or absence of these proteins. The intravenous injection of blood, plasma or serum with the obje..
