Ventricle definition, any of various hollow organs or parts in an animal body. See more. A chamber of the heart that receives blood from one or more atria and pumps it by muscular contraction into the arteries. Mammals, birds, and reptiles have two ventricles

Lateral Ventricles Function, Anatomy & Diagram
The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to
19.1 Heart Anatomy – Anatomy and Physiology
Both ventricles pump the same amount of blood, but the left ventricle must generate a much greater pressure to overcome greater resistance in the systemic circuit. The ventricles are shown in both relaxed and contracting states. Note the differences in the
Enlargement of the ventricles may occur for a number of reasons, such as loss of brain volume (perhaps due to infection or infarction), or impaired outflow or absorption of cerebrospinal fluid from the ventricles, called hydrocephalus or normal pressure hydrocephalus associated with conspicuous brain sulcus..
The ventricles produce and are filled with cerebro-spinal fluid; from the ventricles the cerebro-spinal fluid circulates into the central spinal canal. During a routine ultrasound investigation, the width of the posterior part (‘posterior horn’ or ‘atrium’) of the two lateral ventricles, situated on each side of the midline, is measured.

The ventricles begin to contract (ventricular systole), raising pressure within the ventricles. When ventricular pressure rises above the pressure in the atria, blood flows toward the atria, producing the first heart sound, S 1 or lub.
Hydrocephalus ex vacuo
Hydrocephalus ex vacuo, also known as compensatory enlargement of the CSF spaces, is a term used to describe the increase in the volume of CSF, characterized on images as an enlargement of cerebral ventricles and subarachnoid spaces, caused by encephalic volume loss.
Cilia-based flow network in the brain ventricles
Mammalian third ventricles differ in size and morphology (), yet both the modular organization and the flow domains are largely conserved between mice and rats (compare Fig. 1C with Fig. 4A). The ventricular recesses in the rat are more prominent than in the mouse.
Based on the concepts described along this review of CC being an immune-inflammatory disease affecting both the left and the right ventricles, CMR has the potential to detect not only fibrosis but also myocardium edema and inflammation, in order to further extend seeking for …
