Blood is actually a mixture of plasma, red blood cells, white blood cells, and platelets. Each component is briefly described below:
- Plasma makes up about half of the blood mixture. It is made of water, sugar, fats, proteins and salts. The proteins help blood to clot. Plasma also transports blood cells throughout your body. Plasma delivers nutrients, antibodies, waste products, and chemical messengers.
- Red blood cells deliver oxygen to cells and need. Red blood cells also pick up carbon dioxide so that it can be exported from the body via the respiratory system.
- White blood cells, or leukocytes, help protect the body from infection. Some produce antibodies.
- Platelets help to clot blood.
