Why is it easier to feel a pulse on a superficial artery than a vein?


Answer:
Arteries have a certain expansion and contraction factor that veins don't possess.Blood is carried to the tissues via the arteries, after passing though the capillaries, the blood has been dispersed,so the pulse sensation is lessened.
The pressure differential in an artery is much bigger than that of a vein. The blood pressure in the vein is also much less.Blood pressure in arteries is typically: 120/80 mmHg (systolic on diastolic)Blood pressure in veins ranges from 5-20mmHg and is not so obviously pulsatile.
because the arterial flow is coming FROM the heart after the heart pumps and the veinal blood is returning to the heart.
