Arteries

Arteries are high-pressure blood vessels that carry oxygenated blood away from the heart to all other tissues and organs.

An elastic or conducting artery has a large number of collagen and elastin filaments in the tunica media.

Distributing arteries are medium-sized arteries that draw blood from an elastic artery and branch into resistance vessels.

A circulatory anastomosis is a connection or looped interaction between two blood vessels.

An arteriole is a small diameter blood vessel in the microcirculation system that branches out from an artery and leads to capillaries.

Capillaries, the smallest blood vessels in the body, are part of the microcirculation.
