The book's purpose is to present a description and discussion of the normal and pathologic anatomy and physiology of the lymphatic system. The initial two chapters cover the historical and embryological aspects. The following section discusses the anatomy of the lymphatic microcirculation, collecting ducts, nodes, and main trunks.
