Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Your heart pumps about 1.5 gallons of blood every minute. Over the course of a day, that adds up to over 2, 000 gallons.
Detailed explanation-3: -T=60⋅V⋅r, where T is the total in an hour, 60 due to minutes in an hour, V is the volume of blood per beat, and r is the resting heart rate in beats per minute.
