HUMAN HEART

Introduction:

The human heart stands as the quintessential symbol of life, both metaphorically and
physiologically. Nestled within the protective confines of the chest cavity, this remarkable organ
serves as the powerhouse of the circulatory system, ceaselessly pumping blood throughout the
body to sustain every cell, tissue, and organ with the essential nutrients and oxygen they require
to function.Let's delve into its intricate details:




1. Anatomy:

 The heart is roughly the size of a fist and is located slightly left of the center of the chest,
between the lungs and just behind the sternum (breastbone).
 It is comprised of four chambers: two atria (upper chambers) and two ventricles (lower
chambers). The right atrium receives deoxygenated blood from the body, while the left atrium
receives oxygenated blood from the lungs. The right ventricle pumps deoxygenated blood to the
lungs for oxygenation, and the left ventricle pumps oxygen-rich blood to the rest of the body.
