Ventricular
Ventricular (/vɛnˈtrɪkjʊlər/), derived from the Latin word 'ventriculus' meaning 'little belly', is a term used in anatomy and medicine to refer to a chamber of an organ. In most contexts, it refers to one of the two lower chambers of the heart.
Etymology
The term 'ventricular' is derived from the Latin word 'ventriculus', which means 'little belly'. This is a diminutive form of 'venter', which means 'belly' or 'stomach'. In the context of the heart, it refers to the lower chambers which have a rounded or 'belly-like' shape.
Anatomy
In the human heart, there are two ventricles - the left ventricle and the right ventricle. These are the main pumping chambers of the heart, responsible for pumping blood to the lungs and the rest of the body, respectively. The term 'ventricular' is used to describe anything pertaining to these chambers.
