Document Summary

2 parts: lymphatic vessels and lymphatic tissues/organs: lymphatic vessels: up to 3 l of leaked fluid plus plasma proteins returned to circulatory system, lymphatic tissues/organs: essential in body defense/resistance to disease. Filaments anchor the endothelial cells to surrounding structures: attach blind ended vessels (dead ends) to tissues. Lymphatic vessels start out pretty small, like capillaries, but become larger and larger. Vessels are not actually attached to their neighboring vessels allows them to create bigger spaces (occurs during edema) Clustered along lymphatic vessels: larger clusters where lymphatic vessels converge (inguinal, axillary, and cervical regions, inguinal: pelvic area, axillary: armpit one on either side, cervical: neck. Filter lymph: macrophages remove and destroy microorganisms. Ducts pour lymphatic fluid back into the venous drainage. Cisternae chili: larger than normal lymph node: lymphatic fluid builds up, more sac-like structure. Fight infectious microorganisms that have penetrated epithelial layer and are starting to proliferate in underlying loose ct. Discrete, encapsulated collection of diffuse lymphoid tissue and follicles.
