Pulse is felt due to the rhythmic contraction and relaxation of the

The pulse is the rhythmic expansion and recoil of the arterial walls (particularly the aorta and the main arteries) caused by the pressure wave generated when the left ventricle ejects blood with each heartbeat. It is felt at points where arteries lie close to the surface, such as the radial artery at the wrist or the carotid in the neck. Veins do not produce a pulse because they carry blood under low pressure. The chambers and valves of the heart produce heart sounds, not the peripheral pulse.
