Plasma
Platelets
Red blood cells
White blood cells

  • Plasma is the liquid component of blood. Red and white blood cells and platelets float in your plasma, and together make up whole blood. Your body contains between 5 to 6 quarts (5 liters) of blood.
  • Red blood cells– also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes (from Greek erythros for “red” and kytos for “hollow vessel”, with -cyte translated as “cell” in modern usage), are the most common type of blood cell. These cells deliver oxygen to the tissues in your body. Oxygen turns into energy and your tissues release carbon dioxide. Your red blood cells also transport carbon dioxide to your lungs for you to exhale.
  • White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.
  • Platelets, also called thrombocytes, are tiny cell fragments in your blood that help with clotting. Platelets are your body’s natural bandage to stop bleeding if you’re injured.
