When ventricle contract and A.V. valves close with a jerk, producing the first heart beat sound with low pitch “Lubb”. The second sound of the heart beat with high pitch “Dupp” is produced, when at the beginning of ventricular diastole the semi lunar valves close. The...
The heart features four types of valves which regulate the flow of blood through the heart. These valves have been clearly shown in the labeled diagram of the heart. They permit blood flow in one direction only, and prevent backflow of blood. The four types of valves are: Tricuspid Valve T...
