EfferocytosisIn cell biology, efferocytosis (from efferre, Latin for 'to take to the grave', 'to bury') is the process by which apoptotic cells are removed by phagocytic cells. It can be regarded as the 'burying of dead cells'. During efferocytosis, the cell membrane of phagocytic cells engulfs the apoptotic cell, forming a large fluid-filled vesicle containing the dead cell. This ingested vesicle is called an efferosome (in analogy to the term phagosome). This process is similar to macropinocytosis.
Lymph capillaryLymph capillaries or lymphatic capillaries are tiny, thin-walled microvessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extracellular fluid. Upon entering the lumen of a lymphatic capillary, the collected fluid is known as lymph. Each lymphatic capillary carries lymph into a lymphatic vessel, which in turn connects to a lymph node, a small bean-shaped gland that filters and monitors the lymphatic fluid for infections.
LymphœdèmeUn lymphœdème est un gonflement d'une partie plus ou moins importante du corps à la suite d'une accumulation de liquide lymphatique dans les tissus conjonctifs. Il existe deux types de lymphœdèmes. Le lymphœdème primaire est une malformation du système lymphatique sous forme d'hypoplasie ou d'hyperplasie. Ce type de lymphœdème est cependant rare. Il peut se déclencher de manière spontanée ou à la suite d'un facteur déclenchant (traumatisme, infection, etc.).
