Cardiac Veins

Introduction

Cardiac veins are blood vessels that transport blood from the heart to other organs and tissues. They play an important role in the human body as they provide continuous blood supply. In this article we will look at the structural features and functions of the cardiac veins, as well as their importance in maintaining the health of the cardiovascular system.

The structure of the cardiac veins

The cardiac vein is a large main vessel that arises from the right ventricle of the heart and flows into the superior vena cava. It is one of the largest venous vessels in the human body, its diameter can reach 15 cm. Inside the cardiac vein there are valves that prevent the backflow of blood and help maintain a constant direction of blood flow. In addition, cardiac veins contain endothelial cells, which protect the inner surface of the vessels from damage and infections.

The functions of the cardiac veins include: - Transporting blood from the heart to organs and tissues. - Regulation of blood pressure in the circulatory system. - Participation in the process of blood clotting. - Maintaining normal functioning of the cardiovascular system as a whole.

In addition, the cardiac veins perform an important function in the respiratory system. During inhalation, the superficial veins dilate and provide space for air to fill the lungs. And when you exhale, the superficial venous vessels contract, which helps reduce the volume of the lungs and improve the outflow of venous blood from them.
