Answer 1

Ans :  

Blood transfusion :  

blood transfusion is a way of adding blood to your body after an illness or injury. If your body is missing one or more of the components that make up healthy blood, a transfusion can help supply what your body is missing.

Conditions of blood transfusion:

There are many reasons you might need to receive a blood transfusion. These are just a few of them:

1. You’ve had major surgery or a serious injury and you need to replace lost blood

2. You’ve experienced bleeding in your digestive tract from an ulcer or other condition

3. You have an illness like leukemia or kidney disease that causes anemia (not enough healthy red blood cells)

4. You’ve received cancer treatments like radiation or chemotherapy

5. You have a blood disorder or severe liver problems

Examples of different types of transfusions;

Your blood is made up of several different parts including red and white cells, plasma, and platelets. Whole bloodrefers to blood that has all of them. In some cases, you may need to have a transfusion that uses whole blood, but it’s more likely that you’ll need a specific component

There are several common kinds of blood cell transfusions:

A red blood cell transfusion may be used if you have anemia or an iron deficiency.

Platelets are tiny cells in the blood that help you stop bleeding. A platelet transfusion is used if your body doesn’t have enough of them, possibly because of cancer or cancer treatments.

A plasma transfusion helps replace the proteins in your blood that help it clot. It may be needed after severe bleeding or if you have liver disease.
