Sinus coronarins is a medical term for the coronary sinus, which is a large vein located in the left atrium of the heart. The word consists of three parts: sinus, corona, and -aris/-inus. The first part, sinus, is pronounced /ˈsaɪ.nəs/. The second part, corona, is pronounced /kəˈrəʊ.nə/.

SINUS CORONARINS Meaning and Definition

1. Sinus coronarins refers to the structures within the heart known as the coronary sinus. The coronary sinus is a large vein located in the posterior part of the heart, specifically in the atrioventricular (AV) septum. It is responsible for collecting deoxygenated blood from the cardiac veins and delivering it to the right atrium of the heart.

   The sinus coronarins receives blood from various cardiac veins, such as the great cardiac vein, middle cardiac vein, and small cardiac vein. These veins transport deoxygenated blood that has already circulated through the heart's muscles and coronary arteries, providing them with oxygen and nutrients. This deoxygenated blood is then received by the sinus coronarins, which acts as a reservoir before it is emptied into the right atrium through the coronary sinus ostium.

   The sinus coronarins plays a vital role in the overall functioning of the cardiovascular system. It facilitates the return of deoxygenated blood to the heart, allowing for efficient circulation and oxygenation throughout the body. It serves as a pathway for collected blood to be returned to the right side of the heart, ensuring proper circulation and maintaining the heart's ability to continue pumping oxygen-rich blood to other organs and tissues.

   In summary, the sinus coronarins refers to the coronary sinus, a large vein in the heart that collects deoxygenated blood from various cardiac veins and delivers it to the right atrium.

2. A short trunk receiving most of the veins of the heart, running in the sulcus between the left atrium and ventricle, and emptying into the right atrium between the inferior vena cava and the atrioventricular orifice.
