CORONARY SINUS Meaning and
Definition
-
The coronary sinus is a structure found in the human body that serves as a large vessel responsible for the drainage of blood from the heart muscle itself. It is located within the right atrium of the heart, specifically within the posterior atrioventricular (AV) septum.
The coronary sinus collects deoxygenated blood from the coronary veins, which are small blood vessels that supply the heart muscle with oxygen and nutrients. These coronary veins drain the blood from various areas of the heart, including the left and right ventricles, myocardium, and other cardiac structures. The deoxygenated blood, along with metabolic waste products, then flows into the coronary sinus.
From the sinus, blood is eventually directed into the right atrium through a valve called the coronary sinus valve or the Thebesian valve. The blood mixes with the deoxygenated blood returning from the body and then proceeds into the right ventricle for pulmonary circulation, where it receives oxygen once again. This whole process acts as a pathway for the transport of blood within the heart itself and plays a crucial role in maintaining the overall cardiac circulatory system.
In summary, the coronary sinus is a large vessel located in the right atrium of the heart that collects deoxygenated blood from the coronary veins and serves as a pathway for the drainage of blood from the heart muscle.

Etymology of CORONARY SINUS
The word "coronary sinus" has its origins in Latin and Greek.
The word "coronary" comes from the Latin word "corona", which means "crown". In the context of the heart, "coronary" refers to the arteries that encircle or crown the heart, supplying it with oxygen and nutrients. These coronary arteries branch off from the aorta and deliver blood to the heart muscle.
The word "sinus" is derived from the Latin word of the same spelling, which means "curve" or "bay". In the context of anatomy, "sinus" refers to a cavity or channel where blood collects or circulates.
The "coronary sinus" is a large vein located on the posterior (back) surface of the heart. It collects deoxygenated blood from the heart muscle itself and drains it into the right atrium of the heart.
