ventriküle

Ventriküle is a term used in anatomy to refer to cavities within an organ. Most commonly, it describes the fluid-filled spaces within the brain, known as the cerebral ventricles. These ventricles are a series of interconnected chambers that contain cerebrospinal fluid (CSF). The CSF circulates through these ventricles and also bathes the brain and spinal cord, providing protection, nourishment, and waste removal.

There are four main cerebral ventricles: the two lateral ventricles, one in each cerebral hemisphere, and the third and fourth ventricles located in the midline of the brain. These ventricles are lined with ependymal cells and are connected to each other and to the subarachnoid space by narrow openings. The production of CSF primarily occurs in specialized structures within the ventricles called the choroid plexuses.

The term ventriküle can also be used in the context of the heart. The ventricles of the heart are the two lower chambers responsible for pumping blood out of the heart. The right ventricle pumps deoxygenated blood to the lungs, while the left ventricle pumps oxygenated blood to the rest of the body. The muscular walls of the ventricles are thicker than those of the atria, with the left ventricle having the thickest wall due to the higher pressure required to pump blood systemically.
