Solution
The correct option is A (i) 120 (ii) 80
Contracting phase of the heart is called systole whereas the relaxing phase of the heart is called diastole. And one systole and diastole constitutes a heart beat.
When the heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the walls of the arteries. This is called systolic pressure.
The diastolic pressure on the other hand, indicates the pressure in the arteries when the heart rests or relaxes between beats.
A normal systolic blood pressure is 120 mm of Hg and normal diastolic blood pressure is 80 mm of Hg.
