Assertion : On touching radial artery in our wrist, we feel pulse waves. Reason : The heart beats originate from the sinoatrial node (SA node) on the right atrium.

Step-by-step solution

Pulse is the rhythmic contraction and relaxation in the aorta and its main arteries. It is a regular jerk of an artery. The pulse rate is exactly the same as the heart rate because an artery pulses every time the heart beats. Pulse is usually taken on the radial artery in the wrist but it can be taken on any artery that flows near enough to the surface of the body to be felt. The heart beat originates from the sinoatrial node (SA Node) - pacemaker, which lies in the wall of the right atrium near the opening of the
