The formed elements of the blood include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Of these, leukocytes are primarily involved in the immune response. All formed elements originate in the bone marrow as stem cells (HSCs) that differentiate through hematopoiesis.

Which determines the blood type of a person?

Blood types are determined by the presence or absence of particular antigens on the surface of red blood cells. There are eight main blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive and O negative. The positive and negative refers to your Rh type (once called Rhesus).
