The human heart is a muscular organ that pumps blood throughout the body, providing oxygen and nutrients to the cells and removing waste products. A model of the human heart typically includes a three-dimensional representation of the four chambers of the heart, the major blood vessels, and the valves that regulate blood flow.
The major blood vessels that are part of the heart include the superior and inferior vena cava, which bring deoxygenated blood from the body to the right atrium, and the pulmonary arteries and veins, which carry blood between the heart and lungs for oxygenation.
A model of the human heart can be used to study the structure and function of the heart, as well as various cardiac conditions and diseases. It can also be used to demonstrate the effects of different medications or treatments on the heart.
