What is the structural and functional unit of the heart?
Asked by Female, 31 · 2 months ago
The heart's structural and functional unit is the cardiomyocyte (heart muscle cell). These cells contract in a coordinated way to pump blood throughout the body.

Structural Unit: The structural unit of the heart is the cardiac muscle cell, also known as a cardiomyocyte. These cells form the heart's muscular walls.
Functional Unit: The functional unit of the heart is the cardiac cycle, which includes the coordinated contraction and relaxation of the heart chambers, driven by electrical impulses from the sinoatrial node.
