ventricle

n.
A small cavity or chamber within a body or organ, especially:

1. The chamber on the left side of the heart that receives arterial blood from the left atrium and contracts to force it into the aorta.
2. The chamber on the right side of the heart that receives venous blood from the right atrium and forces it into the pulmonary artery.
3. Any of the interconnecting cavities of the brain.

[Middle English, from Old French ventricule, from Latin ventriculus, diminutive of venter, belly.]

n

A small cavity, such as one of the cavities filled with cerebrospinal fluid in the brain, or the right or left ventricle of the heart.

1. One of a pair of chambers in the heart. The ventricles lie inferior to the atria. The right ventricle receives deoxygenated blood from the right atrium and pumps this blood to the lungs. The left ventricle receives oxygenated blood from the left atrium and pumps the blood through the dorsal aorta to the rest of the body.

2. A fluid-filled chamber in the brain.

(ven-tri-kuhlz)

The two lower chambers of the heart, which receive blood from the atria and pump it into the arteries. (See circulatory system.)

A small cavity or chamber, as in the brain or heart.

• cardiac v. — 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 v. — the median cleft between the two laminae of the brain's septum lucidum.
• fourth v. — a median, horizontally disposed, rhomboid cavity in the hindbrain, between the cerebellum and medulla, containing cerebrospinal fluid.
• gastric v. — stomach.
• laryngeal v. — 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 v. — the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid and communicating with the third ventricle.
• left v. — 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 v. — an extension of the third ventricle into the stalk of the pineal body.
• right v. — 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 v. — 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.
