Detailed explanation-1: -All arteries have a pulse, but it is most easily felt at points where the vessel approaches the surface of the body.

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: -Arteries carry oxygenated blood away from the heart to the tissues of the body. Veins carry blood depleted of oxygen from the same tissues back to the heart. The arteries are the vessels with the “pulse, ” a rhythmic pushing of the blood in the heart followed by a refilling of the heart chamber.

Detailed explanation-4: -The pulse points are the neck (carotid artery), the wrist (radial artery), behind the knee (popliteal artery), the groin (femoral artery), inside the elbow (brachial artery), the foot (dorsalis pedis and posterior tibial artery), the abdomen (abdominal aorta).
