Question

With the help of a chart explain the compatibility of human blood groups.

Answer 1

Hint: Blood is a body fluid in humans and other animals that delivers required materials such as nutrients and oxygen to the cells and aids in the transport of metabolic waste products away from those same cells. In the case of vertebrates it is composed of blood cells suspended in blood plasma.

Complete Answer:
- A blood type which is also known as a blood group is a categorization of blood, depending upon the presence and absence of antibodies and inherited antigenic material on the surface of red blood cells . These antigens might be proteins, carbohydrates, glycoproteins, or glycolipids, based on the blood group system.
- The two most significant blood group systems are ABO and Rh type. They decide someone's blood type that is A, B, AB, and O, with a negative or positive null representing the RhD status for suitability in blood transfusion.
- Blood group AB persons have both A and B antigens on the exterior of their RBCs and their blood plasma does not hold any antibodies against either A or B antigen.
- Blood group A individuals contain the A antigen on the surface of their RBCs and blood serum composed of IgM antibodies against the B antigen.
- Individuals with Blood group B have the B antigen on the surface of their RBCs and the blood serum containing IgM antibodies against the A antigen.
- Persons bearing Blood group O do not have either A or B antigens on the surface of their RBCs and their blood serum contains IgM anti-A and anti-B antibodies.

Blood group	Can donate blood	Can receive
AB+ve	AB+	Every one
AB-ve	AB+, AB-	AB, A, B, O
A+VE	A+, AB+	A+, A-, O+, O-
A-VE	A+, A-, AB+, AB-	A-, O-
B+VE	B+, AB+	B+, B-, O+, O-
B-VE	B+, B-, AB+, AB-	B-, O-
O+VE	O+, A+, B+, AB+	O+, O-
O-VE	Every one	O-

Note: Individuals with group AB blood can receive blood from any group but they are not able to donate blood to any group other than AB. Because of this characteristic feature they are known as universal recipients. Type O individuals are able to receive blood only from a group O individual but they can donate blood to individuals of any ABO blood group. So they are known as universal donors.
