ATRIUM SINISTRUM Meaning and Definition

1. Atrium Sinistrum refers to the left atrium, which is one of the four chambers of the human heart. The heart is a vital organ responsible for pumping blood throughout the body, and it is divided into four separate chambers – two atria (left and right) and two ventricles (left and right). The term "Atrium Sinistrum" is derived from the Latin language, where "atrium" translates to "entrance hall" or "vestibule," and "sinistrum" meaning "left."

   The left atrium is located on the posterior aspect of the heart, situated above the left ventricle and behind the breastbone. Its main function is to receive oxygenated blood from the pulmonary veins and transport it to the left ventricle. The blood then gets pumped into the systemic circulation to supply oxygen and nutrients to various organs, tissues, and cells in the body.

   The atrium sinistrum or left atrium is a thin-walled chamber that contracts to fill the left ventricle during the heart's pumping action. It has specialized muscle fibers called myocardium, which contribute to the contraction and efficient pumping of blood. The left atrium plays a crucial role in maintaining proper blood circulation and ensuring adequate oxygenation of body tissues. Any disturbances or abnormalities in the structure or function of the atrium sinistrum can lead to cardiovascular conditions or diseases, such as atrial fibrillation, mitral valve disorders, or heart failure.

2. A. Of the left side of the heart which receives the blood from the pulmonary veins.

Etymology of ATRIUM SINISTRUM
