- Ventricle (heart)
In the
heart , a ventricle is a heart chamber which collectsblood from an atrium (another heart chamber that is smaller than a ventricle) andpumps it out of the heart.In a four-chambered heart, such as that in
human s, there are two ventricles: theright ventricle pumps blood into thepulmonary circulation for thelung s, and theleft ventricle pumps blood into thesystemic circulation through theaorta for the rest of the body. (SeeDouble circulatory system for details.)Ventricles have thicker walls than the atria, and thus can withstand higher
blood pressure .Comparing the left and right ventricles, the left ventricle has thicker walls because it needs to pump blood to the whole body.
