Solution

The correct option is A
(i) Diastole phase, (ii) Relax, (iii) Systole phase, (iv) Contract

The cardiac cycle is the sequence of events that occurs when the heart beats. In the diastole phase, the heart ventricles relax and helps fill the heart with blood. In the systole, the ventricles contract and pump the blood to the body through the arteries.The ventricular systole and diastole, are considered to be the systole and diastole of the heart beat.

Q. Choose the correct sequence of events in the cardiac cycle:
I. Ventricular systole
II. Blood reaches ventricles
III. A-V valves closes
IV. Atrial systole
V. Semilunar valve closes
VI. Blood goes to major arteries
VII. Semilunar valve opens
VII. Ventricular diastole

Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70 ml. Now, to get the cardiac output, we have to multiply (i)__ with the normal heart rate of (ii)__ beats/min and we get (iii)__ ml/min. This means that in one minute, a normal heart pumps about (iv)__ litres of blood out.
