Blood is made up of liquid and solid. The liquid part, called plasma, is made of water, salts, and protein. Over half of blood is plasma. The solid part of blood contains red blood cells, white blood cells, and platelets. There are four blood types: A, B, AB, or O. Also, blood is either Rh-positive or Rh-negative.
