Heart models show all four chambers of the heart, the valves that separate the chambers, the arteries and veins of the heart, and other important structures for teaching, training, and demonstration of heart anatomy, function, and blood flow.

The human heart is a muscular organ whose function is to create the force to circulate blood throughout the arterial system of the body providing oxygen rich blood and nutrients to all body cells and tissues. The upper right chamber of the heart called the right atrium receives oxygen deficient venous blood returning from the body and pumps it to the lower right chamber called the right ventricle passing through the tricuspid valve. From here the right ventricle pumps the blood to the lungs where it will pick up oxygen fresh blood.

From the lungs the newly oxygenated blood travels back to the heart via pulmonary veins to the upper left chamber called the left atrium. From here the blood is pumped through the mitral valve into the large and powerful left lower chamber called the left ventricle where strong muscular contractions force the blood out from the heart through the aortic valve to travel to all the cells of the body via the arterial system.

Anatomical heart models allow the student to track the pathway of blood from when it enters the right atrium of the heart until it is ejected from the left ventricle of the heart through the aortic valve and into the aorta, to view the arterial and venous blood flow that feeds the myocardium, observe how the valves look and work, the electrical conduction system of the heart, and select pathologies. 

ProHealthcareProducts.com has heart models for active use in teaching and hands-on demonstration of its structure and functions.
