Venous Plexus

Venous Plexus: Overview and Significance

The venous plexus (plexus venosus) is a complex network of veins formed by connecting various venous structures in the body. It is also known by the abbreviations PV (Plexus Venosus), BNA (Bratkovo-Nikolaevo-Abramovskoe venous plexus) and ZhNA (Zheleznodorozhnoe-Nikolaevo-Abramovskoe venous plexus). The venous plexus is an important component of the venous system and performs several important functions in the body.

The formation of the venous plexus occurs due to the connection of many small veins that collect blood from various tissues and organs. This network of veins intertwines and forms a complex architecture, providing efficient drainage and transport of blood throughout the body.

One of the most important functions of the venous plexus is to collect and transport deoxyhemoglobin (low-oxygen blood) from tissues and organs back to the heart and lungs for oxygenation. The venous plexus collects blood containing waste products of metabolism and carbon dioxide and sends it to the portal venous system and then to the right atrium of the heart.

In addition, the venous plexus plays an important role in regulating blood flow and pressure in the body. Thanks to its complex structure and connections to various veins, the plexus is able to adapt to changes in blood flow, ensuring optimal distribution of blood throughout the body and maintaining stable blood pressure.

Some diseases and disorders of the venous plexus can lead to various pathologies and complications. For example, thrombosis (formation of a blood clot in the veins) can lead to impaired blood flow and venous insufficiency. This can happen when a blood clot blocks large veins, preventing the normal transport of blood through the plexus.

In general, the venous plexus is a complex network of veins that plays an important role in the body's blood circulation. Its functions include collecting and transporting blood back to the heart, regulating blood flow, and maintaining optimal blood pressure. Understanding the structure and function of the venous plexus is of great importance to the medical community and helps in the diagnosis and treatment of various venous diseases.
