Which vessels transport blood toward the heart and have valves?
The venous system, or "veins" are responsible for bringing blood back from your peripheral body to the right side of the heart, where it is sent to the lungs for reoxygenation. Veins have one way valves that function to maintain a stable pressure in the venous system, while increasing the efficiency of the heart by preventing backflow of blood in between ventricular beats.
What act as doors between the chambers of your heart?
The heart does not have doors, but it does have valves that could be thought of as doors. They consist of the semilunar valves (the pulmonary semilunar valve and the aortic semilunar valve). The other two are the atrioventricularvalves (tricuspid and bicuspid valves).
What is venous heart?
The part of the heart filled with deoxygenated blood - the right auricle and ventricle of humans. The heart of fishes is venous as it is fully filled with deoxygenated blood.
What is the function of venous valves?
Valves aid in venous return by preventing the back flow of blood.
What maintains venous blood flow?
valves

Channel through which venous blood flows?

Who discovered that venous valves help aid in the return of blood to the heart?
William Harvey
Why are there valves in viens but not arteries?
Venous blood is under very little pressure, so the valves prevent the blood from flowing the wrong way. Arterial blood is under pressure from the heart, so it does not need valves.
A large channel that drains deoxygenated blood is called?
venous sinus
What does the venous system do?
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.
