The lateral ventricles are part of the ventricular system of the brain. Both cerebral hemispheres contain a lateral ventricle. The lateral ventricles are the largest of the ventricles.
Ventricle (heart) In the heart, a ventricle is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium (an adjacent/upper heart chamber that is smaller than a ventricle) primes the pump.
