"auricle" is an acceptable word in written English
It is a noun meaning either "the visible part of the external ear" or "the upper chamber of the heart". For example, "The doctor examined my auricle for any signs of infection."
The outer ear consists of the visible portion called the auricle, or pinna, which projects from the side of the head, and the short external auditory canal, the inner end of which is closed by the tympanic membrane, commonly called the eardrum.
The auricle, the visible portion of the outer ear, collects sound waves and, with the concha, the cavity at the entrance to the external auditory canal, helps to funnel sound into the canal.
Because of its small size and virtual immobility, the auricle in humans is less useful in sound gathering and direction finding than it is in many animals.
Each is roughly cube-shaped except for an ear-shaped projection called an auricle.
The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle.
The most striking differences between the human ear and the ears of other mammals are in the structure of the outermost part, the auricle.
Cetaceans, like all mammals, have a four-chambered heart with paired ventricles and auricles.
The capacity for work of the greatly enlarged quick component of the scallop muscle permits rapid adduction that facilitates swimming by directing jets of water out of the mantle cavity to each side of the hinge line characterized by shell auricles.
The heart, enclosed in a pericardium, comprises a medial ventricle with left and right auricles arising from it.
Blood oxygenated within the ctenidia flows to the auricles and from there to the ventricle, where it is pumped into anterior and posterior aortas.
Bivalves also possess pericardial glands lining either the auricles of the heart or the pericardium; they serve as an additional ultrafiltration device.
