NEET PG DENTAL EXAM

Detailed explanation-1: -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-2: -Calculating SV or HR If you want SV, cover SV with your finger and you are left with CO/HR. For example, if the stroke volume at rest is 70 cm 3 and the heart rate is 70 bpm, then the cardiac output is 70 × 70 cm 3 per minute = 4900 cm 3 per minute. If the SV is 72 cm 3 and the CO is 5400 cm 3/min, what is the HR?
