Detailed explanation-1: -Usually, an adult heart pumps about 5 liters of blood per minute at rest. But when you run or exercise, your heart may pump 3-4 times that much to make sure your body gets enough oxygen and fuel.
Detailed explanation-2: -Therefore, the heart will require approximately 1.02 minutes for pumping 5 liters of blood.
Detailed explanation-3: -In a normal healthy adult, the heart beats 60-100 times in a minute. With each beat, the heart pumps 70 millilitres of blood out of the heart. It can move 5 to 7 litres of blood in one minute and 7600 litres per day. Hence about 70 ml of blood is pumped into the arteries during each heartbeat.
Detailed explanation-4: -According to the Texas Heart Institute, your heart moves about 100 gallons of blood through your body every hour.
Detailed explanation-5: -The average heart pumps 2, 000 gallons of blood per day! In a 70-year lifetime, an average human heart beats more than 2.5 billion times.
