Heart Anatomy

Model comes in multiple 3d format. This is the cutaway version with every part of the heart is exposed.

The human heart is a muscular organ about the size of a fist, located in the chest. It has four chambers: two atria (upper) and two ventricles (lower). The heart pumps oxygen-rich blood from the lungs to the body and returns oxygen-poor blood to the lungs for reoxygenation. It operates through a coordinated electrical system, ensuring efficient circulation.
