ventricle definition and meaning

What is "ventricle"?

The ventricle is a muscular chamber responsible for pumping blood to the rest of the body. It plays a vital role in the circulatory system by receiving blood from the atrium and then contracting to propel it forward into the arteries. The ventricle's muscular walls are thicker and stronger than the atria, enabling it to generate the force needed to push oxygenated blood to the body's organs and tissues. In the heart, there are two ventricles: the left ventricle, which pumps oxygenated blood to the systemic circulation, and the right ventricle, which pumps deoxygenated blood to the lungs for oxygenation. The coordinated contractions of the ventricles ensure the continuous flow of blood throughout the body, sustaining vital functions and maintaining overall cardiovascular health.

ventricle definition and meaning

What is "ventricle"?

The ventricle refers to a series of interconnected cavities filled with cerebrospinal fluid (CSF). These fluid-filled spaces play a crucial role in supporting and protecting the brain. The ventricles are responsible for producing and circulating CSF, which helps cushion the brain, supply nutrients, and remove waste products. The main ventricles in the brain include the lateral ventricles, third ventricle, and fourth ventricle. These interconnected cavities form a complex system that allows for the exchange and circulation of CSF, maintaining the overall health and function of the brain.
