QuestionChoice
Arterioles contribute the most to vascular resistance. Metarterioles are also capable of increasing their resistance to blood flowing into capillaries, but their effect is not as significant as arterioles.

Metarterioles
QuestionChoice
Arterioles contribute the most to vascular resistance. Elastic arteries are conducting vessels, such as the aorta and other large vessels. The aorta has minimal resistance to flow compared to the arterioles.
