Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body. Blood is made up of blood cells and plasma. Plasma say: PLAZ-muh is a yellowish fluid that has nutrients, proteins, hormones, and waste products.

Production of red blood cells is controlled by your kidneys signaling to your body to do this by generating a specific hormone. After that happens, they're created in your body's bone narrow, the soft tissue inside your bones, and are released into your body's bloodstream from there.
