What Is Difference Between Arteries and Arterioles

Arteries are the blood vessels that deliver oxygen rich blood from the heart to the tissues of the body. Arterioles are the smaller arteries which carry blood to the capillary bed. Arteries extend from the aorta and lead to arterioles. Arterioles extend from arteries and lead to capillaries.

What comes first arterioles or arteries?

Blood travels from the heart in arteries, which branch into smaller and smaller vessels, eventually becoming arterioles. Arterioles connect with even smaller blood vessels called capillaries.

What's the difference between arterioles and veins?

Arteries are the blood vessels that carry blood away from the heart, where it branches into even smaller vessels. Finally, the smallest arteries, called arterioles are further branched into small capillaries, where the exchange of all the nutrients, gases and other waste molecules are carried out.
