What are normal blood cells, and what do they do?
Blood has several parts. The liquid part is called plasma. Blood cells are made in the soft center of bones, which is called bone marrow. There are 3 kinds of cells in blood. They are white blood cells, red blood cells, and platelets. Each kind of cell has a special task. Less mature forms of new blood cells are called blasts. As cells mature in the bone marrow, they become smaller and more compact. They are better able to perform their special job. Some new blood cells stay in the bone marrow to grow. Some move to other parts of the body to grow. Your body produces blood cells at a faster rate when your body needs them. This process helps you stay healthy. It helps to understand the role of each kind of blood cell.
