#1 A Normal Heart Pumps Blood Worth 13 Oil Tankers
According to research, a healthy heart pumps just enough blood in a lifetime to fill about thirteen oil tankers. The heart beats more than 30 million times a year, 2.5 billion times during an average lifespan.
To be more precise, a normal heart pumps around 55-80 ml of blood per beat in an adult, and around 25-85 ml of blood per beat in case of children. An average adult’s body contains 5 quarts of blood that continuously circulates throughout the body.
