Coronary Sinus

The coronary sinus (coronary sinus) is an anatomical formation that is located on the inner surface of the heart and connects the right and left chambers. The coronary sinus is one of four cardiac sinuses that circulate blood throughout the body.

The coronary sinus begins at the base of the heart, where it joins the aorta, and continues to the apex of the heart. It has the shape of a crescent and is divided into two parts: upper and lower. The upper part of the coronary sinus is located on the anterior wall of the left ventricle, and the lower part is located on the posterior wall of the right atrium.

One of the main functions of the coronary sinus is to ensure blood circulation in the heart. It mixes arterial and venous blood, which allows you to maintain normal blood pressure and oxygen balance in the body. Also, the coronary sinus plays an important role in regulating body temperature, as it is involved in the process of metabolism between blood and tissues.

However, the coronary sinus can become a site for the formation of blood clots or atherosclerotic plaques, which can lead to poor circulation and the development of cardiovascular diseases. Therefore, it is important to monitor your health and undergo regular medical examinations to identify possible heart problems.

Overall, the coronary sinus is an important part of the cardiovascular system, which circulates blood in the body and is involved in many metabolic processes. However, its functions can be impaired by various diseases, so it is necessary to monitor your health and consult a doctor at the first symptoms of heart problems.



The coronary sinus is one of four veins that run through the brain and heart. It is located at the top of the heart and is shaped like a crescent. The coronary sinus collects blood from the heart and delivers it to the brain through the carotid artery.

The coronary sinus is one of the largest veins in the body. It is about 10 cm long and about 2 cm wide. The coronary sinus is located on the anterior wall of the right atrium and is adjacent to the wall of the right ventricle. It passes through the right atrium and exits through the foramen ovale.

Venous blood flow in the coronary sinus occurs continuously. Venous blood that enters the vein passes through the heart and reaches the brain through the carotid artery. Blood from the brain also passes through the carotid arteries and returns to the heart through the coronary sinus.

Disturbances in the functioning of the coronary sinus can lead to various diseases. For example, if there is insufficient blood flow in the coronary vein, coronary heart disease can develop. Also, disturbances in the functioning of the coronary veins can lead to arrhythmias and other cardiovascular diseases.

To prevent disturbances in the functioning of the coronary vein, it is necessary to monitor your health and undergo regular medical examinations. In addition, it is necessary to lead a healthy lifestyle, eat right and engage in physical activity.
