Pulse
A heartbeat is the contraction and relaxation of the heart muscle, while a pulse is the rhythmic expansion and contraction of an artery as blood is pumped through it by the heart.

The rhythmic expansion and contraction of blood vessels is known as the pulse.pulse
Pulse
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
This process is known as the pulse and is the result of the heart pumping blood into the arteries. As the heart contracts (systole), blood is pushed into the arteries causing them to expand. When the heart relaxes (diastole), the arteries recoil back to their original shape, creating a pulse that can be felt in different parts of the body.
