Lymph Nodes of the Arch of the Azygos Vein

Lymph nodes of the arch of the azygos vein, also known as n. l. arcus venae azygos or PNA, are part of the human lymphatic system. These nodes are located along the arch of the azygos vein, which is an important vein in the superior vena cava system.

Functions of the Lymph Nodes of the Arch of the Azygos Vein

The lymph nodes of the arch of the azygos vein play an important role in protecting the body from infections and diseases. They filter the lymph that flows through them and remove microorganisms, viruses, bacteria and other harmful substances from it. They also help fight cancer cells by engulfing and destroying them.

Structure of the Lymph Nodes of the Arch of the Azygos Vein

The lymph nodes of the arch of the azygos vein are spherical in shape and measure approximately 1 to 2 cm in diameter. They are located along the arch of the azygos vein and are connected to each other by lymphatic vessels. Each node contains lymphocytes - cells responsible for protecting the body from infections and diseases.

Conclusion

The lymph nodes of the arch of the azygos vein are an important part of the lymphatic system and perform functions to protect the body from harmful substances and diseases. Their structure and location along the arch of the azygos vein allow them to effectively filter lymph and remove harmful substances from it. Understanding the lymphatic system and its components is important for maintaining health and preventing various diseases.

Lymphatic ties of the arch of azygos veins

Lymphatic ties (Latin nodus - “node”) are the final sections of the lymphatic flow paths, which consist of a cluster of clusters of thin capillaries formed in the form of nodes, at the junction of which the intradermal lymphatic vessels flow into the subclavian or axillary superficial lymphatic vessels. Each node has a size from several millimeters to several centimeters and can contain up to 30-50 capillaries. The lymph node is enclosed in a connective tissue capsule, which can be clearly defined in superficial nodes and absent in deeply located ones. The node at its location communicates with another vessel from its wide end and with small tissue vessels from the narrow end and is directed towards the central bundle of fibrous connective tissue, and increases the speed of lymph flow, allowing it to avoid the formation of very narrow channels. Lymph nodes are necessary to fight infection and protect the body from foreign agents.
