Cylinder head where valves are-usually. Valves themselves, no.
Antifreeze passes around the engine in special chambers known as galleries. It cools the metalwork of the engine and does not (or should not) enter any part of the combustion, or intake system.

What is the use of valves in the heart.?
The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
What four doors control direction of blood flow through?
valves
What regulates the flow of blood through the heart?
Once blood enters the heart it's flow is regulated by the bicuspid and tricuspid valve which connects the atriums to the ventricles.
Which cardiac structure control blood flow to the heart?
The semilunar valves control the flow of blood from the heart. The aortic semilunar valve controls the flow of blood from the left ventricle to the aorta, and the pulmonary semilunar valve controls the flow of blood from the right ventricle to the pulmonary artery.Pulmonary valve
Where would you expect the blood to pass through valves?
There are a set of 4 valves in the heart in a part of the heart called the "skeleton". These are the Mitral (a bicuspid), Tricuspid, Aorta, and the Semiliunar valves. There are valves in the veins which prevent back flow.
How do valves ensure the continuous unidirectional flows of blood?
Valves allow forward blood flow. Valves prevent the back flow of the blood. You have beautiful small muscles in your ventricles. They are called as papillary muscles. They are attached to the bicuspid and tricuspid valves and simultaneously contract, during the contractions of the ventricles, to prevent the collapse of the cusps of the valves. The aortic and pulmonary valves prevent the back flow by there anatomical advantage. This way, the valves ensure the continuous unidirectional flow of blood.
What does a valve guard the entrance to?
The heart valves ensure that once blood has passed through them, into or out of the heart, it can not flow backwards.
How shut off valves work?
the pipe is closed by a gate or ball that cuts off flow through the pipe
Do the aortic and pulmonary valves control the flow of the blood into the heart?
No, semilunar valves control the flow of blood out of the heart.
How are heart valves similar to valves in veins?
in both the valves blood flow in one direction.
Do valves prevent the flow of blood?
Valves prevent the backflow of blood
What does a valves do?
Valves in general control the flow of something. They serve as regulators.
