Question

How much amount of blood is pumped during each heartbeat?


  1. 100 ml

  2. 55 ml

  3. 50 ml

  4. 70 ml


Solution

The correct option is D

70 ml


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.
