Introduction:

In this experiment, our objectives consisted of performing tests in order to identify blood types; learning about the function and shapes of different blood components; and understanding the importance of blood typing and its uses. In the world of medicine, knowing about blood typing and, more importantly, having the ability to type blood is an indispensable tool. Medical procedures ranging from blood transfusions to organ transplants to obstetrical interventions require a solid understanding of blood typing. Being able to understand the ABO and Rh blood types is a fundamental building block to learning about the complexity of blood chemistry and the wonders it unravels.
According to Martini et al. the ABO blood types and the Rh system are based on antigen-antibody immunological responses (650). Antigens are proteins located on the surface of red blood cells; plasma membranes and these can trigger an immune response—a protective defense mechanism. Immune systems recognize these antigens as “normal”, and thus in a healthy individual these are recognized as “self” or “non-foreign” and the body will ignore them. The presence of absence of specific surface antigens on erythrocytes’ plasma membranes determines blood type. From this rationale, it is known that there are four blood types characterized by their respective surface antigens: Type A with A antigens, Type B with B antigens, Type AB with both A and B antigens, and Type O distinguished by its lack of…
