a small cavity or chamber, as in the brain or heart.
ventricle of Arantius
1. the rhomboid fossa, especially its lower end.
fourth ventricle a median cavity in the hindbrain, containing cerebrospinal fluid.
ventricle of larynx the space between the true and false vocal cords.
lateral ventricle the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid.
left ventricle the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body.

pineal ventricle an extension of the third ventricle into the stalk of the pineal body.
right ventricle the lower chamber of the right side of the heart, which pumps venous blood through the pulmonary trunk and arteries to the capillaries of the lung.

right ven·tri·cle (RV),

[TA]
the lower chamber on the right side of the heart that receives the venous blood from the right atrium and drives it by the contraction of its walls into the pulmonary artery.
Synonym(s): ventriculus dexter [TA]

right ventricle

the relatively thin-walled chamber of the heart that pumps blood received from the right atrium into the pulmonary arteries to the lungs for oxygenation. The right ventricle is shorter and rounder than the long conical left ventricle. The chordae tendineae of the tricuspid valve of the right ventricle are finer than the coarse strands of the chordae tendineae of the left ventricle. See also heart.

right vent·ri·cle

(rīt ven'tri-kĕl) [TA]
The lower chamber on the right side of the heart that receives the venous blood from the right atrium and drives it by the contraction of its walls into the pulmonary artery.

cardiac ventricle
the single fetal cardiac ventricle, formed by the looping of the bulboventricle; divided later by the growth of the interventricular septum as a projection from the wall of the bulboventricle.
fifth ventricle
the median cleft between the two laminae of the brain's septum lucidum.
fourth ventricle
a median, horizontally disposed, rhomboid cavity in the hindbrain, between the cerebellum and medulla, containing cerebrospinal fluid.
gastric ventricle
stomach.
laryngeal ventricle
a variably developed cavity of the larynx that opens into the laryngeal vestibule by a cleft between the vestibular and vocal folds; well developed in dogs and horses and especially certain apes.
lateral ventricle
the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid and communicating with the third ventricle.
left ventricle
the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body.
pineal ventricle
an extension of the third ventricle into the stalk of the pineal body.
right ventricle
the lower chamber of the right side of the heart, which pumps venous blood through the pulmonary trunk and arteries to the capillaries of the lung.
third ventricle
a vertically disposed, ring-shaped space that contains cerebrospinal fluid and that communicates anteriorly with the lateral ventricles and caudally with the cerebral aqueduct within the diencephalon between the two thalami.
