Is Arteriole an Artery?

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.

Are arterioles arteries?

Arteries and arterioles

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.

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.
