Why do humans have different blood groups !!#shorts #ytshorts #shortsviral #trending #trendingshorts #facts #viralshorts #shortvideo #Arjuna Sagar Explainers
Every human has a unique blood group because of specific proteins, called antigens, present on the surface of red blood cells. These antigens—mainly the A, B, AB, and O types—are inherited from our parents and determine which blood type we have. Blood types are important because they affect how our bodies react to blood transfusions, medical procedures, and even organ transplants.
In addition to the main blood groups, each person also has an Rh factor, which is another protein that may or may not be present on the red blood cells. If you have this protein, your blood type is positive (for example, A+ or O+). If you do not have it, your blood type is negative (for example, B- or AB-).
The Rh factor is inherited from your parents, just like your blood group. About 85% of people worldwide are Rh positive, making it much more common than Rh negative. The presence of the Rh factor doesn’t affect health in daily life, but it is very important in situations like pregnancy and blood transfusions. For example, Rh incompatibility between a mother and her baby can cause health problems if not managed carefully.
In summary, blood groups and Rh factor make each person’s blood special and unique, playing a crucial role in safe medical care all around the world.
