Lymph Nodes Parasternal

Parasternal lymph nodes (lat. nodi lymphoidei parasternales) are a group of lymph nodes located along the internal mammary vessels, along the thoracic lymphatic duct.

The circumsternal lymph nodes drain lymph from the anterior and lateral walls of the chest, diaphragm, liver, stomach, spleen, pancreas and other abdominal organs. Lymph flows from these nodes into the right lymphatic duct.

The periasternal lymph nodes play an important role in the body's immune defense, being part of the lymphatic system. Damage to these nodes by tumor or inflammation can interfere with the outflow of lymph from vital organs.

The lymphatic system is a complex network of vessels and organs that are responsible for cleansing the body of harmful substances and bacteria. One of the important components of this system are the lymph nodes located in various parts of the body.

Periasternal lymph nodes (parathoracic or parasternal) are a group of lymph nodes located in the armpit and chest. They play an important role in protecting the body from infections and inflammatory processes, and also help cleanse the lymph.

The structure of the periathoracic lymph node consists of two main parts: capsule and parenchyma. The capsule is a hard shell that protects the node from damage and infection. Parenchyma is the internal structure of an organ, consisting of lymphatic channels, follicles and drainage tubules.

Functions of the perithoracic lymph nodes: - Filtration of lymph and protection of the body from germs and viruses; - Participation in the regulation of immunity and restoration of damaged cells
