Word: Atrioventricular Valve
Part of Speech: Noun
Definition: The atrioventricular valve is one of two important valves in the heart. It helps control the flow of blood between two parts: the atria (the upper chambers of the heart) and the ventricles (the lower chambers). The valve makes sure that blood flows in one direction, preventing it from going back into the atrium after it has moved into the ventricle.
Usage Instructions: - You can use "atrioventricular valve" when talking about the structure and function of the heart. It's often discussed in medical or biological contexts.
Example Sentence: "The atrioventricular valve opens to allow blood to flow from the atrium into the ventricle."
Advanced Usage: In more advanced discussions, you might differentiate between the two specific types of atrioventricular valves: the mitral valve (on the left side of the heart) and the tricuspid valve (on the right side of the heart).
