ventricle
n.one of the two lower chambers of the heart that pumps blood out to the body. It is a strong, thick-walled part of the heart that sends blood to the lungs or the rest of the body.
n.one of the two lower chambers of the heart, responsible for pumping blood to the systemic or pulmonary circulation. In human anatomy, the left ventricle pumps oxygenated blood to the body, while the right ventricle sends deoxygenated blood to the lungs.
“The left ventricle is the strongest part of the heart.”
“During a heart attack, the blood flow to the ventricle can be blocked, leading to serious complications.”
“The anatomical structure of the ventricle is designed to withstand the high pressure required to propel blood through the entire circulatory system, distinguishing it from the thinner-walled atria.”
“People exposed to higher levels of nighttime light showed thickening in the wall of the left ventricle (one of the chambers of the heart).”
From late Middle English, from Latin ventriculus (“the belly”), diminutive of venter (“the belly”). Doublet of ventriculus.
