Journal of Phlebology and Lymphology (1983-8905) is a peer reviewed open access journal. This scientific journal aims to provide the most complete and reliable source of information on the current developments in the field of Phlebology and Lymphology. The emphasis will be on publishing quality papers rapidly and making them available to researchers worldwide at no cost.

Journal of Phlebology and Lymphology is devoted entirely to function, mechanism, pathology of Lymphatic system and venous diseases. The journal keeps interventionalists, phlebologists, wound care specialists that treat acute, chronic and emergency wounds, and allied health professionals up-to-date by providing novel and authoritative information about experimental, clinical and basic science, medical research and clinical studies on a variety of Lymphatic system and diseases of the veins.

Contributors are welcome to publish high quality clinical, and laboratory research papers, case series, reviews, guidelines, techniques, and practice manuscripts related to all aspects of venous, lymphatic diseases, and wound care.Lymph 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 and associated cells (notably white blood cells) is known as lymph. Each lymphatic capillary carries lymph into a lymphatic vessel, which in turn connects to a lymph node. Lymph is ultimately returned to the venous circulation.

Lymphatic capillaries are slightly larger in diameter than blood capillaries, and have closed ends (unlike the loop structure of blood capillaries). Their unique structure permits interstitial fluid to flow into them but not out. The ends of the endothelial cells that make up the wall of a lymphatic capillary overlap. When pressure is greater in the interstitial fluid than in lymph, the cells separate slightly, like the opening of a one-way swinging door, and interstitial fluid enters the lymphatic capillary. When pressure is greater inside the lymphatic capillary, the cells adhere more closely, and lymph cannot escape back into interstitial fluid. Attached to the lymphatic capillaries are anchoring filaments, which contain elastic fibers. They extend out from the lymphatic capillary, attaching lymphatic endothelial cells to surrounding tissues. When excess interstitial fluid accumulates and causes tissue swelling, the anchoring filaments are pulled, making the openings between cells even larger so that more fluid can flow into the lymphatic capillary.

Lymph capillaries have a greater internal [oncotic]pressure than blood capillaries, due to the greater concentration of plasma proteins in the lymph.
