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. Blood carries out many critical functions in the body.
# In one day, the heart pumps nearly 2,000 gallons of blood. In a 70-year lifetime, it pumps about 51 million gallons. # In the average lifetime, the heart beats 2.5 billion times. # The human heart is fully developed about eight weeks after conception, when the embryo is only about one inch long.
