Detailed explanation-1: -Pulse beat is measured by superficial arteries present on the body surface. Arteries carry oxygenated blood.

Detailed explanation-2: -The pulse can be measured using the radial artery in the wrist or the carotid artery in the neck. Heart rates vary from person to person.

Detailed explanation-3: -To check your pulse over your carotid artery, place your index and middle fingers on your neck to the side of your windpipe. When you feel your pulse, look at your watch and count the number of beats in 15 seconds. Multiply this number by 4 to get your heart rate per minute.

Detailed explanation-4: -The arterial pulse is the abrupt expansion of an artery resulting from the sudden ejection of blood into the aorta and its transmission throughout the arterial system.

Detailed explanation-5: -When the heart pushes blood into the aorta, the blood’s impact on the elastic walls creates a pressure wave that continues along the arteries. This impact is the pulse. All arteries have a pulse, but it is most easily felt at points where the vessel approaches the surface of the body.
