Answer 2

..... The heart keeps contracting and relaxing. During the contraction phase, the blood within the heart is pumped out. During the relaxation phase, the blood fills into the heart from the veins. This blood is then pumped out, in the next contraction phase.

Diastolic pressure is the pressure exerted by the blood on the walls of the arteries when the heart is in the relaxed state. The pressure exerted by the blood on the walls of the arteries when the heart contracts, is the systolic pressure. The difference between these two pressures (called the pulse pressure) is felt as the pulse. The normal pulse pressure is 30–40 mm Hg.

A large difference between these two pressures would be felt as a bounding pulse. It can normally occur in a person soon after exercising. It returns to normal in 10–15 minutes. Otherwise it is seen in anaemia, certain heart conditions etc.
