Blood Basics
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets.

Blood has some following functions:

  • 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

Blood Circulation
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 9 pints.
