Since blood looks the same to the naked eye, people may assume that blood is just blood. However, there are four main groups of blood types and each person has a different blood type.
Blood contains basic components such as red cells, white cells, platelets, and plasma. In addition, there are markers, also called antigens, that are made up of proteins and sugars that our bodies use to identify blood cells within its own system and the surprising fact is, not everybody carries these markers.
Here are the four main blood type groups:
- Type A – Blood type has a marker known as “A”
- Type B – Blood type has a marker known as “B”
- Type AB – Blood type contains both “A” and “B” markers
- Type O – Blood type has neither “A” or “B” markers
Because millions of Americans need transfusions every year due to loss of blood, medical assistants are needed to assist doctors and surgeons in performing transfusions. Medical assistants learn to understand everything there is to know about the human body and with blood being the main component delivering nutrients to the various systems in our bodies; it is an essential body of knowledge to learn as a medical assistant.
