Verified step by step guidance

Understand the function of heart valves: Heart valves are structures within the heart that ensure blood flows in one direction, preventing backflow.

Identify the types of heart valves: There are four main heart valves - the tricuspid valve, pulmonary valve, mitral valve, and aortic valve.

Learn the location and function of each valve: The tricuspid valve is between the right atrium and right ventricle, the pulmonary valve is between the right ventricle and pulmonary artery, the mitral valve is between the left atrium and left ventricle, and the aortic valve is between the left ventricle and aorta.

Explore how valves open and close: Heart valves open and close in response to pressure changes in the heart chambers during the cardiac cycle, ensuring unidirectional blood flow.

Recognize the importance of valve integrity: Proper functioning of heart valves is crucial for efficient blood circulation and preventing conditions such as regurgitation or stenosis.
