NEET PG DENTAL EXAM

Detailed explanation-1: -The arteries branch into smaller and smaller vessels, eventually becoming very small vessels called arterioles. Arteries and arterioles have muscular walls that can adjust their diameter to increase or decrease blood flow to a particular part of the body.

Detailed explanation-2: -A muscular artery (or distributing artery) is a medium-sized artery that draws blood from an elastic artery and branches into “resistance vessels” including small arteries and arterioles. Their walls contain larger number of smooth muscles, allowing them to contract and expand depending on peripheral blood demand.

Detailed explanation-3: -Arteries: These strong, muscular blood vessels carry oxygen-rich blood from your heart to your body. They handle a large amount of force and pressure from your blood flow but don’t carry a large volume of blood.
