Human Heart - Free Essay Examples and Topic Ideas

The human heart is a vital organ responsible for pumping blood throughout the body. It is located in the chest cavity and approximately the size of a closed fist. The heart consists of four chambers, two atria and two ventricles, which work together to cycle oxygenated blood through arteries to various organs and deoxygenated blood back to the lungs for oxygenation. It is encased in a protective sac called the pericardium and is regulated by an intricate system of electrical impulses and hormones. The heart plays a critical role in maintaining overall health and well-being, and any dysfunction or disease can have serious consequences.
