Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including:
transporting oxygen and nutrients to the lungs and tissues
forming blood clots to prevent excess blood loss
carrying cells and antibodies that fight infection
bringing waste products to the kidneys and liver, which filter and clean the blood
regulating body temperature
The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood. An average-sized man has about 12 pints of blood in his body, and an average-sized woman has about nine pints.
