What is another word for left atrium?
Pronunciation: [lˈɛft ˈatɹi͡əm] (IPA) 
The left atrium is a crucial anatomical component of the heart, responsible for receiving the oxygen-rich blood from the lungs and pumping it into the left ventricle. It is often referred to as the "left auricle" due to its ear-like shape, or the "atrium cordis sinistri" in Latin medical terminology. Another synonym for the left atrium is the "left atrial appendage," which is a smaller, pouch-like extension of the atrium. The term "mitral atrium" is also used to describe the left atrium, as it leads to the mitral valve which is responsible for regulating blood flow between the atrium and ventricle.
