Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.

How do arterioles regulate blood flow into capillaries?
Sphincters
Why are valves separating the atrium and ventricles of the heart?
To regulate the flow of blood and to control it's speed.
Why does the heart has valves?
Valves are the "doors" which allow the proper amount of blood into each ventricle of the heart so it does not "explode" or push too much into the body. When high blood pressure occurs the culprit can be a defective valve that is leaking or failing to open and close properly. Not many people have that type of high blood pressure. There are many types of high blood pressure which doctors can determine by listening to the valves in the heart or elsewhere.
Do capillaries have valves if no why?
Capillaries are very small blood vessels which act as the transporting medium between the oxygenated blood in the arteries (excluding the pulmonary) and the deoxygenated blood in the veins. As they are so small of approximately 5-20 micro-metres in diameter, they do not need valves, as there is a distinct flow from the arterioles supplying the capillary with blood, and the venules draining the capillary within the double circulation.
Why does the heart need valves?
The reason why we need we need valves in our heart is because the valves in our heart will open and close. When the valves in our heart open, they allow blood to go into places in our body where blood is needed. When the blood passes through, the valve closes. They regulate the blood flow.
Why does the human heart need valves?
The reason why we need we need valves in our heart is because the valves in our heart will open and close. When the valves in our heart open, they allow blood to go into places in our body where blood is needed. When the blood passes through, the valve closes. They regulate the blood flow.
Which sphincters function as regulatory valves that reduce the flow of blood through a network of capillaries when they contract and constrict the arterioles?
Precapillary sphincters
What is the important of valves?
Valves are hollow shaped devices that regulate the flow of afluid opening or closing or by just obstructing various passageways. Their importance in the human is to prevent back flow of blood in the veins. By doing this it also stops blood from clotting in the veins.
Why does blood move faster through your capillaries?
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
How do blood and blood vessels work properly?
signals from the heart regulate the flow of blood . there are some values which regulate the backward flow of blood
How the muscles in an artery regulate blood flow?
There are no muscles in arteries. Arterioles have muscles which can close them, but which has no normal flow control. (Used is stress/shock conditions only) Capillaries have a muscle which can stop all flow through it - it responds to oxygen pressure and is the ultimate control of blood flow.
