Iron overload in organs may increase the risk of various diseases such as liver failure, cirrhosis of the liver, damage of the pancreas, other heart diseases. Therefore, by maintaining the iron level in the body, periodic blood donation can reduce the risk of various heart disease and liver disease. And reduce the possibility of heart attack by 88%

According to the American Red Cross, it is said to be able to save the lives of one or more people by drinking a cup of blood. The United States needs about 36,000 pints of blood a day, and 6.8 million people donate blood every year. However, blood donation has no drawbacks. Each donor has undergone a small physical exam, but there are still some minor side effects. When you donate, you sit or lie on the reclining chair, and your arm extends above the armrest. The health care provider wraps the blood pressure cuff or tourniquet around the upper arm and injects more blood into the vein. After cleaning the inside skin of the elbow, the health care provider inserts the sterilized needle into the thin plastic tube and the blood bag. Put the needle in the arm for about 10 minutes, or during blood donation.

Blood donation is divided into groups according to who donates blood. "Homogeneous" (also known as "homogeneous") blood donation refers to a donor that stores blood in a blood bank and enters into an unknown recipient. An "instructed" donation is when a person (usually a family member) donates blood to a particular individual for transfusion. If supply is established, target donation will be relatively small. Donation of "Alternative Donor" is a combination of these two, which is common in developing countries such as Ghana. In this case, recipients' friends or families will donate blood to replenish stored blood used for blood transfusion and ensure continuous supply. This is called a "home" donor if a person's bloodstream is sent back to the donor later (usually after surgery). The blood used to produce the drug can be made from a provision provided only for the provision or manufacture of an allograft.
