Are Arterioles Arteries

An artery carries blood away from the heart, and distribute throughout the body by its succeeding smaller branches. Eventually, the smallest branch of the artery is called arterioles, which further divide into tiny vessels to form the capillary bed.

What type of artery is an Arteriole?

Arterioles are small arteries that deliver blood to capillaries. Arterioles control blood flow through capillary beds by contracting or dilating the the size of the lumen, and therefore the tunica media layer contains concentric rings of smooth muscle to do this.

Are blood vessels arteries?

Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart.
