ARTERIOVENOUS ANASTOMOSIS Meaning and
Definition
-
Arteriovenous Anastomosis refers to a direct connection between an artery and a vein, bypassing the usual capillary network. It is a natural physiological shunt that allows for increased blood flow and immediate transfer of blood from the arterial system to the venous system. These anastomoses can be found in various tissues throughout the body and have different roles depending on their location.
In the skin, arteriovenous anastomoses have a significant role in thermoregulation. When the body needs to dissipate heat, these anastomoses dilate, allowing a rapid bypass of warm arterial blood directly into the venous system. This process leads to increased heat loss, helping to cool down the body. Conversely, during cold exposure, these anastomoses constrict to preserve body heat.
Arteriovenous anastomoses are also important in the circulatory system. In certain cases, they can serve as surgical connections between arteries and veins to provide alternative routes for blood flow, bypassing blocked or damaged blood vessels. These procedures are commonly performed in vascular surgery to treat conditions like ischemia or dialysis access.
Overall, arteriovenous anastomoses are essential structures that serve multiple functions in the body, including thermoregulation and rerouting blood flow. Understanding their anatomy and physiology is crucial in the medical field for diagnosis, treatment, and management of various conditions related to cardiovascular health.

Etymology of ARTERIOVENOUS ANASTOMOSIS
The term "arteriovenous anastomosis" can be broken down into two parts: "arteriovenous" and "anastomosis".
1. Arteriovenous:
- Arterio-: This prefix is derived from the Latin word "arteria", which means artery. It refers to a blood vessel that carries oxygenated blood away from the heart to the rest of the body.
- Venous: This term is derived from the Latin word "vena", which means vein. It refers to a blood vessel that carries deoxygenated blood from the tissues back to the heart.
Therefore, the term "arteriovenous" describes the connection or interaction between arteries and veins.
2. Anastomosis:
- Anastomosis: This term is derived from the Greek word "anastomōsis", which means "an opening".
