What is a Lymphangion? A lymphangion is a segment of a lymphatic collector located between two valves and is considered the functional unit of the peripheral lymphatic system. It has the ability to contract autonomously and is often referred to as the “microlymphatic heart.” 

Lymphangion:

Contraction The lymphangion contracts rhythmically and in a coordinated manner, generating a series of impulses that automatically propagate along the segment. The frequency and strength of contractions depend on the level of lymph filling within the lymphangion. When it reaches a certain level of filling, resulting in an internal pressure of approximately 3-4 cm of H2O, the muscular walls contract. This muscular contraction promotes the emptying of lymph in both directions. 

Valves inside the lymphangion play a crucial role in ensuring the one-way flow of lymph. These valves open in the direction of flow and prevent backflow into the preceding lymphangion. In this way, a centripetal flow, directed toward the center of the lymphatic system, is facilitated. 

Through its rhythmic contractions and lymph emptying ability, the lymphangion actively contributes to lymphatic drainage. This process is essential for removing excess fluids, waste products, and pathogens from peripheral tissues, ensuring the proper functioning of the lymphatic system. 

In conclusion, a lymphangion is a segment of a lymphatic collector situated between two valves. Its rhythmic contractions and lymph emptying capacity play a crucial role in lymphatic drainage and contribute to the proper functioning of the peripheral lymphatic system.
