Organization
The lymphatic system can be broadly divided into the conducting system and the lymphoid tissue.
- The conducting system carries the lymph and consists of tubular vessels that include the lymph capillaries, the lymph vessels, and the right and left thoracic ducts.
- The lymphoid tissue is primarily involved in immune responses and consists of lymphocytes and other white blood cells enmeshed in connective tissue through which the lymph passes. Regions of the lymphoid tissue that are densely packed with lymphocytes are known as lymphoid follicles. Lymphoid tissue can either be structurally well organized as lymph nodes or may consist of loosely organized lymphoid follicles known as the mucosa-associated lymphoid tissue (MALT).

Famous quotes containing the word organization:
“I will never accept that I got a free ride. It wasn’t free at all. My ancestors were brought here against their will. They were made to work and help build the country. I worked in the cotton fields from the age of seven. I worked in the laundry for twenty- three years. I worked for the national organization for nine years. I just retired from city government after twelve-and-a- half years.”
—Johnnie Tillmon (b. 1926)
“The methods by which a trade union can alone act, are necessarily destructive; its organization is necessarily tyrannical.”
—Henry George (1839–1897)
“I would wish that the women of our country could embrace ... [the responsibilities] of citizenship as peculiarly their own. If they could apply their higher sense of service and responsibility, their freshness of enthusiasm, their capacity for organization to this problem, it would become, as it should become, an issue of profound patriotism. The whole plane of political life would be lifted.”
—Herbert Hoover (1874–1964)
