Förmakshålans

Förmakshålans, also known as the atrial appendage or auricle, is a small, ear-shaped pouch that projects from the upper part of the right atrium of the heart. It is a muscular pouch that can contract and expand, and its primary function is to increase the volume of the right atrium, allowing it to hold more blood. The right atrial appendage plays a role in atrial contraction and can influence cardiac output. It is also a common site for thrombus formation, especially in individuals with atrial fibrillation. The presence of varying sizes and shapes of the atrial appendage has been noted, and its characteristics can be visualized using imaging techniques such as echocardiography and cardiac magnetic resonance imaging. While its precise clinical significance is still being researched, its involvement in various cardiac conditions underscores its importance in cardiovascular health.
