The larger trunks, such as the left and right 1. ducts and those uniting 1. glands, consist of three coats similar to those of arteries but somewhat thinner. They empty into the right and left 1. ducts, and are provided with valves similar to those of the veins and intercommunicate with each other, forming extensive plexuses. As they approach their distal terminations they consist of a single layer of endothelium. They have their origins in the shape of a system of intercommunicating spaces between the ultimate elements of the connective ti ue in the 1. sinuses, and by apertures (stomata) upon the free surfaces of serous membranes, tne cavities of which latter are a umed by some to be lymph-spaces.
