Unlike the endothelial cells of blood capillaries, lymphatic endothelial cells are not joined by tight junctions, nor do they have a continuous basal lamina. The gaps between them are so large that bacteria, lymphocytes, and other cells and particles can enter along with the tissue fluid. In surgery, soft tissues are dissected. By contrast, components of the (hard) bony skeleton are sawed, chiselled, or drilled. Soft tissues include all types of tissue except bone, i.e., all epithelial, muscle, and nerve tissue, as well as connective tissue excluding bone. 5. Nonencapsulated lymphatic tissue called MALT includes all of the following except: A. tonsils. B. Peyer patches. C. lymph nodes. D. diffuse lymphatic tissue. 6. Bacteria and debris are actively removed from the lymph by _____ in the sinuses of lymph nodes. A. trabecular cells B. germinal cells C. macrophages.

They include the thymus, spleen, tonsils, and appendix, along with some special tissue in the gut: The thymus: The thymus is located in the thoracic cavity, just under the neck ...
