![]() It is also possible for the recipient to get other blood groups from the donor however, blood types must be compatible for the mixing. Although it is best to have an exact match for blood groups during transfusion, it is not always compulsory. For example, people with blood group A can safely receive blood group A from others during a blood transfusion. Therefore, the recipient and the donor need to have the same blood types. The wrong combination of blood types can trigger adverse reactions or dangerous immune responses, which can also be life-threatening. ![]() It is clear that if two different blood groups in a person's body are mixed, the blood can clump. Many people died during blood transfusions (transferring blood from one person to another) because of wrong blood mismatch. Before the introduction of blood groups, the doctors used to think that all people have the same blood groups. The different types of blood groups were introduced in 1901 by an Austrian scientist Karl Landsteiner. The process of blood transfer from donor to recipient is termed ' blood transfusion'. The one who gives blood is called a donor, while receiving the blood is named a recipient. Blood cells must be matched while transferring the blood from one human to another. Besides, different people may or may not have the same blood type. However, a healthy person typically consists of approximately 5 liters (12 pints) of blood circulating throughout the body. The definite amount of blood in humans usually depends on their size and can vary from one person to another. The composition usually varies from one human to another. Moreover, it also contains erythrocytes and leukocytes and millions of molecules with their specific roles and functionalities. It is usually made up of the combination of the red & white blood cells and platelets, suspended in a fluid known as plasma (the liquid form of blood). What is blood?īlood is a fluid connective tissue and the essential parts of the circulatory system in the human body. Before discussing the different types of blood groups, let us first discuss the definition of blood and how its types are determined. In this article, we are discussing the major blood group types and their descriptions. In particular, blood type in humans usually depends on which gene they have inherited from their parents. Although it is present in all humans, it has different types. It takes part in most of the body's activities. Blood is one of the most important elements of the human body.
