VENA TERMINALIS Meaning and
Definition
-
The vena terminalis is a term used in anatomical and medical contexts to refer to a specific blood vessel in the human body. It is a large vein located in the right atrium of the heart, where it enters and communicates with this chamber. The vena terminalis is also known as the terminal vein or the sinus venarum.
Anatomically, the vena terminalis starts at the upper portion of the right atrium and curves superiorly, following a path that roughly parallels the atrioventricular septum. It receives blood from several sources, including the left atrium, coronary sinus, and various cardiac veins. This blood eventually flows into the right atrium through the vena cava.
Functionally, the vena terminalis plays a role in the drainage of deoxygenated blood from both the systemic and coronary circulations. It helps to ensure the proper circulation and oxygenation of blood throughout the body. Additionally, the vena terminalis is important in certain medical procedures, such as cardiac surgery, where it may be cannulated or accessed for diagnostic or therapeutic purposes.
Understanding the anatomy and function of the vena terminalis is essential for healthcare professionals, particularly cardiologists and cardiac surgeons, in order to diagnose and treat cardiovascular conditions effectively.
