Which statement is true of the right atrioventricular valve? it is also called the mitral valve it is open during ventricular diastole it transmits oxygenated blood it is opened by the pull of chordae tendineae it consists of 2 leaflets

The statement that is true of the right atrioventricular valve is: "it is opened by the pull of chordae tendineae".

Here's why:

1. The right atrioventricular valve is also known as the tricuspid valve, not the mitral valve. The mitral valve is the left atrioventricular valve.

2. The right atrioventricular valve is indeed open during ventricular diastole, which is when the ventricles are relaxed and filling with blood. However, this is also true of the left atrioventricular (mitral) valve, so without more context, it's not specific to the right atrioventricular valve.

3. The right atrioventricular valve does not transmit oxygenated blood. It transmits deoxygenated blood from the right atrium to the right ventricle. The oxygenated blood is handled by the left side of the heart.

4. The right atrioventricular valve is indeed opened by the pull of the chordae tendineae, which are heart strings that prevent the valve from inverting.

5. The right atrioventricular valve consists of three leaflets, not two. The one with two leaflets is the mitral valve.
