Question

What is the ABO blood classification based on?

Answer 1

Question 1. The best answer is C - antigen on the red blood.

The ABO  blood classification is based on the red blood cells. In summary:

1. blood type A has antigen A  on the red cell membrane.

2. blood type B has antigen B on the red cell membrane.

3. blood type AB has both antigen A and B on the cell membrane.

4. blood type O has no antigen at all on the red cell membrane.

Question 2. the best answer is b - transportation of oxygen.

Sickle cells have an abnormal type of hemoglobin that is unable to  carry oxygen  in the same capacity that normal, healthy hemoglobin does.

Answer 2

The blood grouping is classified on the basis of surface antigen. Sickle cell anemia decreases the transportation of oxygen within the body.

Further Explanation:

A blood group system or ABO blood groups are classified on the basis of the inherited characteristics of the erythrocytes (red blood cell). It is determined by the presence of type A and type B antigen on the surface red cells. It was first discovered by Karl Landsteiner in 1901. The people with type A antigen will have type B antibodies in their serum. The individual with type O blood group does not possess any type of antigen, whereas type AB possesses both the antigens. Blood group O is the most commonly occurring blood group type across the world.

Sickle cell anemia or sickle cell disease is an inherited disorder or it can be transmitted from generation to generation. The normal red cells are small, biconcave and circular in structure. They are more flexible and can easily cross the vessel. In sickle cell disease conditions, the cells are of crescent or sickle-shaped. The change in the structure makes it rigid and sticky due to which the stuck in the vessel. It results in blocking the blood flow. In this disease, the red blood cells die more frequently than usualthat cause a decrease in the number of red blood cell.
