Peritoneal Cavity Lymphatics

Abstract

Lymphatic drainage of particulate matters from the peritoneal cavity occurs mainly from lacunae located in the diaphragm. These are a triple-layered structure consisting of mesothelium, a loose network of connective tissue and endothelium. Absorption of particles may occur via gap junctions, through the cells or via vesicles. Whole blood can be removed fairly rapidly from the peritoneal cavity. Respiration plays an important role in the absorption of particles through lymphatics. Intra-abdominal pressure and posture are other factors which influence lymphatic flow rate in the peritoneal cavity. Little is known about the influence of drugs on lymphatic flow rate from the peritoneal cavity.
