A ventricle is one of two large chambers located toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle.

In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [ 1 ][ 2 ] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF).
During ventricular systole the ventricles contract and vigorously pulse (or eject) two separated blood supplies from the heart—one to the lungs and one to all other body organs and systems—while the two atria relax (atrial diastole). This precise coordination ensures that blood is efficiently collected and circulated throughout the body.
ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system. Ventricles occur among some invertebrates. Among vertebrates, fishes and amphibians generally have a single ventricle, while reptiles, birds, and mammals have two.
3 lis 2023 · Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
7 cze 2024 · There are two ventricles: the right ventricle pumps blood into the pulmonary artery which takes the blood through the pulmonary circuit, and the left ventricle pumps blood into the aorta for systemic circulation to the rest of the body. Ventricles have thicker walls than the atria, and thus can create the higher blood pressure.
12 kwi 2024 · The apical trabecular portion is the most distinctive in each ventricle being characteristically coarse in the right ventricle (Figure 1.4.1A) and fine in the left ventricle. In a similar way, the muscular ventricular septum can be considered in terms of inlet, apical trabecular and outlet portions.
