What is the ventricular system?
The ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF).
What is the function of the ventricular system of the brain?
Aside from cerebrospinal fluid, your brain ventricles are hollow. Their sole function is to produce and secrete cerebrospinal fluid to protect and maintain your central nervous system.

How do you remember CSF flow?
Here is a simple mnemonic to remember the CSF flow through the ventricular system:
- “Liquid Inside The Cerebrum Flows Around Subarachnoid Space”
- Liquid = Lateral Ventricles.
- Inside = Interventricular Foramina.
- The = Third Ventricle.
- Cerebrum = Cerebral Aqueduct.
- Flows = Fourth Ventricle.
- Around = Apertures.
Where is the ventricular system?
the brain
The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
What are the 4 ventricles?
The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These cavities, known collectively as the ventricular system, consist of the left and right lateral ventricles, the third ventricle, and the fourth ventricle….

How many ventricles are in the brain and what is their function?
The brain’s ventricular system is comprised of four ventricles as well as small structures which connect each ventricle called foramina. In this way, the ventricles are linked to each other to function as they should. The ventricles are essential for maintaining the central nervous system (CNS).
How many ventricles are there?
four
The ventricles (in purple). The ventricles are four interconnected cavities distributed throughout the brain that produce and contain cerebrospinal fluid (CSF). The two lateral ventricles are C-shaped chambers found in the cerebral hemispheres (one in each hemisphere).
How can we remember where the ventricles are located?
Each half of the heart has an upper collecting chamber, the atrium, and a lower pumping chamber, the ventricle. You can remember their location because A comes before V. The atrium is above the ventricle.
How many ventricles are in the brain?
