a small conical pouch projecting from the upper anterior part of each atrium of the heart

the externally visible cartilaginous structure of the external ear

The external ear, or that part of the ear which is prominent from the head.

An angular or ear- shaped lobe.

An instrument applied to the ears to give aid in hearing; a kind of ear trumpet.

The chamber, or one of the two chambers, of the heart, by which the blood is received and transmitted to the ventricle or ventricles; - so called from its resemblance to the auricle or external ear of some quadrupeds. See Heart.

The outer ear; one of the two chambers of the heart which receive the blood from the veins.

1. Auricula ( 1, 2, 3). 2. In botany, zoology, and entomology, any ear- shaped appendage. 3. A form of ear- trumpet for the use of the deaf.

The external cartilage of ear; superior cavities of heart.

The external ear:- pl. the two ear- like cavities of the heart.

The outer ear; one of the two smaller cavities of the heart.

A chamber of the heart.

The external ear; an ear- shaped part; an ear- trumpet.

Two muscular cavities of the heart, resembling ears, and placed above the ventricles.

The external ear, or that part which is prominent from the head.

The outside ear; a venous chamber situated at the base of the heart, resembling the external ear.

The external ear; any earlike lobed appendage; the upper or anterior chamber on each side of the heart.

Carbon dioxide still exhales up through your lungs, but the vein back to the left auricle is routed through the carburetor and supercharged with oxygen. – Sjambak by John Holbrook Vance

And another set of valves has grown up between the auricle and the ventricle on each side of the heart. – A Handbook of Health by Woods Hutchinson

Beside them could be seen other elevated objects of auricle shape, set in rows or circles like a festooning of child peppers strung up for preservation. – The Lone Ranche by Captain Mayne Reid

Having passed through its proper vessels, it accumulates in the left auricle. – The American Reformed Cattle Doctor by George Dadd

These alternate contractions and dilatations can have but one result, namely, to force the blood from the auricle to the ventricle, and from the ventricle, on the right side, by the pulmonary artery to the lungs, and on the left side by the aorta to the system. – Fathers of Biology by Charles McRae

The canal forms a curved tube, which can be straightened to a considerable extent for purposes of examination by pulling the auricle upwards and backwards. – Manual of Surgery Volume Second: Extremities--Head--Neck. Sixth Edition. by Alexander Miles Alexis Thomson

They form larger and larger vessels until they become two large veins in each lung, and pour their contents into the left auricle. – A Practical Physiology by Albert F. Blaisdell

Its function is to force the venous blood through the pulmonary veins to the right auricle; thence to be distributed over the body. – First Person Paramount by Ambrose Pratt

The right auricle and ventricle are completely separated from the left auricle and ventricle by a thick septum or wall, so that there is no communication between the right and left sides of the organ. – Special Report on Diseases of Cattle by U.S. Department of Agriculture J.R. Mohler

Many animals move the auricle in the direction of the sound. – A Practical Physiology by Albert F. Blaisdell

These two veins bring venous blood from all parts of the body, and pour it into the right auricle, whence it passes into the right ventricle. – A Practical Physiology by Albert F. Blaisdell

I'd like to know about that right auricle of his heart. – The Bramleighs Of Bishop's Folly by Charles James Lever

Open the left auricle, and notice the entrance of the pulmonary veins, and the passage into the ventricle. – A Practical Physiology by Albert F. Blaisdell

Their purpose is to serve as valve stops, to prevent the valve from being thrown, by the force of the blood stream, back into the auricle. – Physiology and Hygiene for Secondary Schools by Francis M. Walters, A.M.

The canal now being folded upon itself in heart- shape, next becomes constricted in situations, marking out the future auricle and ventricle and arterial bulb, which still communicate with each other. – Surgical Anatomy by Joseph Maclise

The right ventricle forces the blood through the lungs and into the left auricle. – Physiology and Hygiene for Secondary Schools by Francis M. Walters, A.M.

Each heart consists again of two compartments- an auricle and a ventricle. – Surgical Anatomy by Joseph Maclise
