Although the power of judicial review isn't explicitly stated in the Constitution, the authority is implied in Article III, and in general by virtue of the Supreme Court's role as head of the Judicial branch of government. Article III, Section 1 begins:
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.
About one thirteenth or 7.5 percent of your body weight is blood. a 13 stone man has about 14 pounds or 4 litres of blood surging around his body. When the body is resting the adult human heart pumps out about 4 litres of blood per minute, this rises to 27 litres per minute under vigorous exercise.
