Origin of ventricle:
1350–1400; ME < L ventriculus belly, ventricle. See venter , -i -, -cle1

ventricle, heart ventricle(noun)
a chamber of the heart that receives blood from an atrium and pumps it to the arteries
Any small cavity within a body; a hollow part or organ, especially:
One of two lower chambers of the heart.
One of four cavities in the brain.
Origin: From ventricule, from ventriculus, diminutive of venter
a cavity, or one of the cavities, of an organ, as of the larynx or the brain; specifically, the posterior chamber, or one of the two posterior chambers, of the heart, which receives the blood from the auricle and forces it out from the heart. See Heart

In the heart, a ventricle is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium primes the Pump. Interventricular means between two or more ventricles, while intraventricular means within one ventricle. In a four-chambered heart, such as that in humans, there are two ventricles: the right ventricle pumps blood into the pulmonary circulation to/for the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. Ventricles have thicker walls than atria and generate higher blood pressures. The physiologic load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by the atria to fill the ventricles. Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs. The mass of the left ventricle, as estimated by magnetic resonance imaging, averages 143 g ± 38.4 g, with a range of 87––224 g.
