a.

Summary Introduction

To determine:

Whether the following blood type could be donated to a person with type B blood: blood type A.

Introduction:

In humans, four different types of blood groups are found- A, B, AB, and O. These are differentiated on the basis of the surface protein or presence or absence of Rh factor. Blood transfusion is usually not safe if the blood of compatible type is not received, because on RBC surface glycoproteins are present which act like antigens. On blood transfusion, these antigens behave as a foreign particle which leads to damage of the cells.

In type, A blood group, type A antigen is present on the surface of RBC and their plasma has anti-B type of antibody. In type B blood group, the RBCs surface have type B antigen and plasma has anti-A antibody. The blood group of these individuals is identified as type B.

Summary Introduction

To determine:

Whether the following blood type could be donated to a person with type B blood: blood type AB.

Introduction:

In AB group, both type of antigen i.e. type A or type B antigens are present on RBC’s surface, but their plasma lack antibodies. Due to this, the individual having AB blood group is identified as a universal acceptor. In type B blood group, the RBCs surface have type B antigen and plasma has anti-A antibody. The blood group of these individuals is identified as type B.
