Question

Quizplus · Accepted Answer

Veins are known as capacitance vessels because they have a high compliance or distensibility, which enables them to stretch and store blood. This allows them to act as a reservoir that can be tapped into in times of increased demand for blood, such as during exercise or hemorrhage. Venules are small veins that connect capillaries to larger veins, but they do not have the same capacitance function as larger veins. Arteries and arterioles are known as resistance vessels because they contribute to vascular resistance and help regulate blood pressure. Capillaries are the site of exchange of nutrients and waste products between the blood and tissues.
