An essential fluid for human life, blood cannot be synthesized outside a living human body. However, blood from a healthy person can often be used effectively by another person who is in need of this life-sustaining fluid. Every day, many sick and injured people need blood or blood products in order to stay alive and heal. In times of disaster and war, the need for blood and blood products increases dramatically. A blood bank is a health-care process in which a healthy person deposits a small portion of his or her blood, usually about one pint, in a sanitary blood-drawing process. The blood is then stored under sanitary conditions for a period of time. Later, the blood is transfused into another person. |
