Love Your Heart: A Comprehensive Guide to Heart Health

The heart is a vital organ that pumps blood throughout the body, delivering oxygen and nutrients to the tissues and organs that need them. It is a muscular organ located in the chest, between the lungs, and is roughly the size of a fist. The heart is made up of four chambers – the right atrium, the left atrium, the right ventricle, and the left ventricle – and is surrounded by a protective sac called the pericardium.
