What about blood group?</h3>
- According to the presence or absence of antibodies and hereditary antigenic compounds on the surface of red blood cells, blood is classified according to its type.
- Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
- The genes that a person got from their parents determine what blood type they have.
- There are numerous systems for classifying blood types, but ABO is the most popular one.
- The ABO group is divided into four main categories: A, B, O, and AB.
- There are eight more blood types within these groupings.
- Each of the eight blood types has a particular ability to save lives.
- The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.
