Tricuspid valve

This video tutorial explores the anatomy and function of the tricuspid valve, a key component of the heart's atrioventricular valves. It details the valve's structure, including its three cusps and the subvalvular apparatus, which prevents backflow of blood. The tutorial also explains how the tricuspid valve contributes to heart sounds and offers additional resources for further learning.

What is the primary function of the tricuspid valve in the heart?

• To pump blood into the aorta

• To prevent backflow of blood into the right atrium

• To oxygenate the blood

• To regulate heart rate

Which structures connect the tricuspid valve to the ventricular walls?

• Pulmonary veins

• Coronary arteries

• Chordae tendineae

• Atrial septum

How many cusps does the tricuspid valve have?

• Two

• Three

• Four

• Five

What sound is associated with the closing of the atrioventricular valves?

• Click

• Thump

• Lub

• Dub

What governs the opening and closing of heart valves?

• Nerve signals

• Electrical impulses

• Muscle contractions

• Pressure gradients
