Blood clot
Heart to arteries to capillaries to veins.
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
Capillaries play a role in regulating body temperature through the process of vasodilation and vasoconstriction. When the body heats up, capillaries near the skin surface widen (vasodilate), allowing more blood to flow and dissipating heat. Conversely, when the body is cold, capillaries constrict (vasoconstrict) to reduce blood flow and conserve heat. This mechanism helps maintain homeostasis and overall thermal balance in the body.
Arterioles are small blood vessels that help regulate blood flow and blood pressure within tissues by controlling the amount of blood that enters capillaries. They are key in directing blood to specific areas of the body based on the body's needs at any given time.
From the capillaries, blood will flow into the veins and pump the un-oxygenated blood back to the heart.
