Blood groups are a classification of the blood in a body that is based on the presence or absence of inherited antigenic substances on the surface of red blood cells. These antigens can come in a number of forms, namely carbohydrates, proteins, glycoproteins and glycolipids. The ones that are there depend on the blood group system.
These red blood cell surface antigens can stem from one allele and together they form a blood group system. A person's blood group is inherited from their parents and represent contributions from both the mother and the father. The International Society of Blood Transfusion have classified a total of 30 human blood groups. It is important to have blood groups, in a medical sense, to aid successful blood transfusions.
Certain people with certain blood groups can only accept blood from the same system, others have blood groups that can be accepted by most humans. Classifying blood allows hospitals to keep a supply of each group from donors ready for any transfusions that may need it. Blood donors are a crucial part to this system and although thousands of people donate blood, there is still a short supply of some of the rarer groups.
Blood group systems are categorized by two sub systems. These are the ABO blood group system and the Rh blood group system. The ABO blood group system is the most important blood group system regarding human blood transfusion. The associated anti A and anti B antibodies are usually Immunoglobin M. These antibodies are produced in the first few years of life be sensitization to a variety of foods, bacteria and viruses.
The Rh blood group system is the second most important blood group system for human blood transfusion. The most prominent antigen is the D antigen as it is the most likely to provoke an immune system response from the other five antigens.

∙ 14y agoBlood groups are a classification based on what antigens are present within blood. Antigens are substances that cause the production of antibodies and can cause immune responses. The two main types of blood classification are the ABO classification and the Rhesus classification. The ABO classification is the part that is denoted by whether your blood type is A, B, AB, or O. Group A has what is known as the A antigen, group B has the B antigen, group AB has both, and group O has neither one. The Rhesus classification is what determines if your blood type is positive or negative. It is based on the Rhesus factor, also known as the RhD antigen. If a person possesses the Rhesus factor, they are classified as positive, and if they do not possess it, they are classified as negative.

∙ 14y agoThey are important because not all blood types mix.
A blood infusuion from the wrong group may do more harm than good.

What is the importance of the study of blood?
The importance of doing a microscopic study of blood is to find even the small possible problems. Because blood is made of very tiny components, it becomes very helpful to directly examine them with the human eye.
Duffy blood group system?

What are blood groups and what is their importance?
Blood type is determined by antibodies and antigens present in red blood cells antibodies A and B for blood group A and B, when there's no antibodies it is group AB, when both antibodies A and B is present then it is group O
