How many types of blood does the human body have?

Answer 1

i dont know but there are erythrocytes or the red blood. the leukocytes or the white blood and the platlets or hema or thrombocytes. all of those types make up the yellowish blood called the plasma

Answer 2

In terms of the A, B, O blood types, a person would have only one type unless we are talking about a pregnant woman; a fetus does not necessarily have the same blood type as the mother. There is, however, a sense in which people do have two types of blood in their bodies. There is oxygenated blood, fresh from the lungs, and deoxygenated blood, in which the oxygen has been used up.
