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).
A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. Four valves are usually present in a mammalian heart and together they determine the pathway of blood flow through the heart.
3 sie 2023 · This article aims to discuss the development, anatomy, and function of the ventricles of the heart with an accompanying heart diagram to aid in understanding. Additional discussion regarding disorders of the ventricle (both congenital and acquired) will also be included.
Now, the ventricular system consists of four ventricles: two lateral ventricles, the third ventricle and the fourth ventricle. CSF flows from the lateral ventricles through the left and right interventricular foramina, also called the foramina of Monro, to the third ventricle.
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.
