A lymphangion is the functional unit of a lymph vessel that lies between two semilunar (half moon-shaped) valves. [1] [2] Lymph vessels are channels larger than the lymph capillaries that have thicker walls, valves in their lumen and smooth muscles in their walls, thus lymph vessel lymphangion is muscular and capable of contracting on its own.

A lymphangion is the term for the space between two semilunar valves in a lymphatic vessel, functional unit of the lymphatic system. Lymph fluid can only flow forward through lymphangions due to the closing of valves after fluid is pushed through by fluid accumulation, smooth muscle contraction, or skeletal muscle contraction.

2024年1月3日 · Each lymphangion, defined as the segment between two valves, can typically exhibit systole and diastole. When a lymphangion is relaxed, the inflow (or upstream) valve will open (given...

2021年1月15日 · A lymphangion is a segment of a lymphatic vessel bound by semilunar valves on either side. When circular smooth muscles of these vessels contract, lymph is moved from one lymphangion to the next. The valves ensure unidirectional movement of lymph fluid.

This paper reviews the results of the studies performed mainly by the Russian anatomists on the functional anatomy of lymphangion as a structural and functional unit of lymphatic vessel. One of the peculiar features of functional anatomy of lymphangion is the …

A lymphangion is a morphological/functional unit of lymphatic vessels defined as the section of a lymphatic vessel between two adjacent lymphatic valves. Lymphangions have highly organized endothelial and smooth muscle layers in their walls.

2022年12月4日 · Knowledge regarding the mechanisms by which lymph is transported to the blood circulation has markedly advanced from a system originally considered driven by extrinsic compression to one where intrinsic constrictions of lymphatic chambers termed ‘lymphangions’ are recognised as a primary means for propelling lymph.

2021年12月21日 · Here, a fabrication technique (gravitational lumen patterning or GLP) is developed to create a lymphangion-chip. This organ-on-chip consists of co-culture of a monolayer of endothelial lumen surrounded by multiple and uniformly thick layers of muscle cells.

To determine the effects of lymphangion interaction on lymph flow, we adapted an existing mathematical model of a lymphangion (characterizing lymphangion contractility, lymph viscosity, and inertia) to create a new lymphatic vessel model consisting of several lymphangions in series.

A lymphangion is a segment of a lymphatic vessel that is located between two valves and is capable of contracting due to its muscular system. It receives lymph from the distal lymphatics and becomes distended before contracting to propel the lymph forward.
