The Heart Contraction and Valve Function Demonstration Model is an educational tool designed to visually and interactively demonstrate the cardiac cycle, including the contraction and relaxation of the heart, as well as the opening and closing of its valves. This model provides a clear and hands-on way to understand the mechanics of blood flow through the heart.
Interactive Cardiac Cycle Demonstration: By manually operating the transmission mechanism, users can simulate the contraction and relaxation of the heart.
Valve Functionality Display:
During ventricular contraction (systole): The left ventricle's mitral valve and the right ventricle's tricuspid valve close, while the aortic and pulmonary semilunar valves open, allowing blood to be pumped from the ventricles into the pulmonary artery and aorta.
During ventricular relaxation (diastole): The aortic and pulmonary semilunar valves close, while blood flows from the left and right atria into the respective ventricles.
Visual Representation: Features color-coded sections (blue for deoxygenated blood and red for oxygenated blood) to clearly illustrate the flow of blood through the heart's chambers and vessels.
Educational Tool: Ideal for students, educators, and medical professionals to study and teach the dynamics of heart function and valve operation.
The Heart Contraction and Valve Function Demonstration Model offers an engaging and effective way to learn about the heart's critical role in circulation, making it an essential resource for anatomy and physiology education.
