Detailed explanation-1: -What are arterioles? An arteriole (är-’tir-ē-, ōl) is a very small blood vessel that branches off from your artery and carries blood away from your heart to your tissues and organs. Arterioles are small arteries that link up to capillaries, which are smaller yet.

Detailed explanation-2: -Capillaries are the smallest blood vessels in the body.

Detailed explanation-3: -The key difference between arteries and arterioles is that arteries are the blood vessels that carry blood from the heart while arterioles are smaller arteries which receive blood from the larger arteries and pass to capillaries.

Detailed explanation-4: -The arteriolar lumen regulates the flow of blood through the capillaries. Venules are the smallest veins and receive blood from capillaries. They also play a role in the exchange of oxygen and nutrients for water products.
