The purpose of this study was to describe the morphology of the whole lymphatic way: from capillaries to thoracic duct including cisterna chili using scanning electron microscopy and Evan's technique. We observed the lymph vascular wall that is: the endothelial surface, the muscular layer and the adventitial one. All these vessels were covered by an endothelial surface, with raised nuclei and long cell axes oriented parallel to the direction of flow. The borders between adjacent endothelial cell were often seen and open junctions were noted in lymphatic capillaries. The technique we used, permitted the removal of connective tissue by HC1 hydrolysis, so that smooth muscle cells could be examined. The latter showed a great variety of aspects and a very irregular course. The adventitial layer was thin in capillaries and became complex in thoracic duct where collagen fibers and connective elements were seen.

UI MeSH Term Description Entries
D008208 Lymphatic System A system of organs and tissues that process and transport immune cells and LYMPH. Lymphatic Systems
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
