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 narrow cleft below the corpus callosum, within the diencephalon between the two thalami.

left ven·tri·cle (LV),

[TA]
the lower chamber on the left side of the heart that receives the arterial blood from the left atrium and drives it by the contraction of its walls into the aorta.
Synonym(s): ventriculus sinister [TA]

left ventricle (LV)

the thick-walled chamber of the heart that pumps blood through the aorta and the systemic arteries, the capillaries, and back through the veins to the right atrium. It has walls about three times thicker than those of the right ventricle and contains a mitral valve with two flaps that controls the flow of blood from the left atrium. The left ventricle occupies about half the diaphragmatic surface of the heart and is longer and more conical than the right ventricle, narrowing caudally to form the apex. The chordae tendineae of the left ventricle are thicker, stronger, and less numerous than those in the right ventricle. See also chordae tendineae.

left ven·tri·cle

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

Left ventricle

The large chamber on the lower left side of the heart. The left ventricle sends blood to the aorta and the rest of the body.

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.
