A pulse is caused by the alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. The arteries become distended during systole, or heart contraction, and their walls contract during diastole, when the heart relaxes. The pulse, measured in beats per minute, can be felt at a number of points throughout the human body, but is most commonly palpated at the wrist or neck. Where are the pulse points in the lower limbs? Discuss
