Not all blood circulation of participation of blood in the human body, 20- 25% of the blood is stored and " stored the blood bank " on spleen, liver, lung, skin,etc. Inside, the spleen is largest " stores the blood bank " in the human body ,Can store the blood of human body total blood volume 20%.

The activity of exhaling the old and inhaling the new of human blood compositions is very much active, nearly have 1/120 of the erythrocyte (namely 2 billion erythrocytes)s every day in the human body Old and feeble, death, the average life span of the leucocyte is about 7- 14 days, the life-span of the blood platelet is shorter, about 7- 9 days. Besides, the human bone marrow has strong compensation functions, under the circumstances that certain condition is stimulated, bone marrow hematopoietic function can rise to normal 6- 8, one healthy people succeed about 200 billion erythrocytes innately while being every, 120 billion small boards of blood, namely each healthy adult, the new born blood cell is equivalent to the total amount of the human blood cell every year.
