Key Concepts

Atrioventricular Valves

Atrioventricular valves are located between the atria and the ventricles of the heart. They function to allow blood to flow from the atria into the ventricles during diastole and prevent backflow during systole, maintaining unidirectional blood flow within the heart.

Semilunar Valves

Semilunar valves are situated at the exits of the ventricles, controlling the flow of blood into the major arteries, such as the aorta and pulmonary artery. Their crescent-shaped cusps ensure that blood does not return to the ventricles after being pumped out into the circulation.

Cardiac Anatomy and Blood Flow

This concept encompasses the study of the heart's structure, including its chambers, valves, and major vessels, and the pathways through which blood is circulated. A clear understanding of the sequence of blood flow—from the atria to the ventricles and then out to the body or lungs—is crucial for understanding normal cardiac function and identifying any deviations from it.
