Auricle of Heart：

Auricle of heart refers to the small ear-shaped appendage on the right and left of heart. It is connected to the atrium of the heart and helps the heart to pump blood. The auricle of heart is composed of myocardium, which is made up of two parts: the septum, which separates the auricle from the atrium and ventricle, and the auricular appendage, which is shaped like an ear.

The auricle of the heart plays an important role in the contraction and relaxation of the heart. When the auricle contracts, it helps to push the blood out of the atrium into the ventricle. When the auricle relaxes, it helps to draw blood into the atrium. This creates an effective pumping action which helps to maintain blood circulation throughout the body.

The auricle of the heart also serves as an important link between the atrium and ventricle. It has several small openings which make it possible for blood to flow between these two chambers. It also acts as a buffer between them, which helps to ensure that the pressure in the atrium and ventricle remain balanced.

In certain medical conditions, such as mitral valve prolapse, the auricle of the heart can become enlarged, causing the heart to beat inefficiently. In such cases, doctors may recommend surgery to repair the malfunctioning valve and restore the heart’s normal functioning.

Therefore, the auricle of the heart is an important part of the cardiovascular system. By playing an important role in the contraction and relaxation of the heart, it helps to ensure the flow of blood throughout the body and maintain healthy cardiovascular function.
