What is the name of the atrioventricular valve found in the left heart?

The mitral valve, also known as the bicuspid valve, is the atrioventricular valve located on the left side of the heart. It separates the left atrium from the left ventricle. The primary function of the mitral valve is to allow blood to flow from the left atrium into the left ventricle while preventing backflow during ventricular contraction. This is crucial for maintaining efficient circulation, as it ensures that oxygenated blood can be effectively pumped from the left ventricle into the aorta and subsequently distributed to the body.

In the context of the other options, the tricuspid valve is located on the right side of the heart and functions similarly to the mitral valve, but it is not associated with the left heart. The pulmonic valve and aortic valve are semilunar valves, positioned at the outflow of the ventricles (pulmonary artery and aorta respectively) and play different roles in the cardiac cycle. The aortic valve, while crucial for systemic circulation, is not an atrioventricular valve, which is specific to the connections between atria and ventricles.
