Function of blood cells – 15 million restored every second
Blood cells are of two types – red and white. The red blood cells transport gases; these carry oxygen from the lungs to the different parts of the body and return the carbon dioxide from the different parts to the lungs. The white blood cells are involved in maintaining the immunity of the body. In addition, there are special cells called platelets. Every second, about 15 million of these blood cells die as new cells take their place.
