What is "left ventricle"?

The left ventricle is the largest and strongest chamber of the heart responsible for pumping oxygen-rich blood to the rest of the body. It receives blood from the left atrium and contracts forcefully to propel the blood into the aorta, which then distributes it to all organs and tissues. The left ventricle's thick muscular walls allow it to generate high pressure and maintain systemic circulation, supplying oxygen and nutrients to support the body's metabolic needs.
