How many liters of blood does an average adult human have?
Scientists estimate the volume of blood in a human body to be approximately 7 percent of body weight. An average adult body with a weight of 150 to 180 pounds will contain approximately 4.7 to 5.5 liters (1.2 to 1.5 gallons)of blood. An average child with a body weight of 80 pounds will have approximately half the amount of blood as an adult.

How much blood is in a pint?

Which group has B antibodies?
Group A - has A antigens on the red blood cells and B antibodies in the plasma. Group B - has B antigens on the red blood cells and A antibodies in the plasma. Group AB - has both A and B antigens on the red blood cells and no antibodies. Group 0 - has no antigens but has both A and B antibodies in the plasma.
How is blood type determined?
The type of blood is determined by inherited genes and is divided in different groups. One of the most important blood group system is the ABO System: There are four major blood groups determined by the presence or absence of the two antigens: A and B on the surface of the red cells.
