Firstly, the right ventricle is not filled with water. It is filled with blood. The tricuspid valve prevents the leakage of blood back into the right atrium when the ventricle enters systole (contraction).
(MORE IN DETAIL!)
Grammatically its not Firstly its First off. You are right the ventricle is not filled with water its mostly RBCs, plasma and WBCs are traveling else where in the body. Also yes "The tricuspid valve prevents the leakage of blood back into the right atrium when the ventricle enters systole (contraction)." is correct. But if you need it to be more detailed this is where it gets complicated: When the action takes place there is 2 sounds that the tricuspid valve can make 1: a "Dupp & Lubb" sound do to a recoil of blood into the next pulmonary artery. If Fluid does back track you get an extra noise. Like "swashing". If this 3rd noise doesnt happen (which is good) this makes it possible for there heart beat noises to take place. Sinoatrial node or known better as SA node generates action potentials on its own (pacemaker's usually come in play if this fails). Impulse passes along fibers to mass of specialized tissue (atrioventricular node). From AV node, the impulses, moves through bundle of His AV Bundle. The impulse divides into L & R branches underneath endocardium, then it gives rise to Purkinje fibers which causes the ventricular walls to contact as said above.

When the tricuspid valve closes this is known as tricuspid regurgitation. In this condition, the tricuspid valve doesn't close and blood backs up into the atrium.
Yes it is closed. In systole the ventricles are contracting and if the valve would be open the blood would regurgitate back in the atrium.

What happens to the tricuspid and miltral valves when the heart contracts?
they open to allow the blood through then close again so the blood can't flow back
When do the bicuspid valves open and close?
The bicupid and tricuspid valves close during ventricular contraction. This prevents the backflow of blood from the ventricles to the atria.
Are the tricuspid valves of the heart also called semilunar valves?
The tricuspid valves are different from the semilunar valves. The tricuspid valve is the right atrioventricular valve.
The first sound of a cardiac cycle occurs when?
closure of the mitral and tricuspid valves.
Where in the heart are the bicuspid and tricuspid valves located?
The bicuspid and tricuspid valves are located between the atria and the ventricles. The bicuspid or mitral valve is on the left, and the tricuspid is on the right.
What happens when the AV valves are Ventricular contraction?
the valves close
What happens when the ventricular walls contracts?
The bicuspid valve opens and the tricuspid valve closes.
Why do blood cant flow backward to atrium when ventricles contract?
The tricuspid and bicuspid valves block blood from coming back into the atria.
Can you list all of the valves in the heart?
Aortic, Bicuspid,tricuspid and Pulmonic valves.
What are the names for the two different sets of heart valves?
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.
What valve of the heart has three valves with chordae tendineae?
No, only the atrio ventricular, or the the tricuspid and bicuspid valves, have heart strings
What is the medical term meaning reverse flow of blood through the mitral or tricuspid valves?
Mitral regurgitation or tricuspid regurgitation is the medical term meaning backflow of blood through the mitral or tricuspid valves, respectively.
