Develop practices sustainable management of soils with the use of green roofs, paths, contour plowing and incorporation of natural barriers and minimum tillage. This may include a good system of farmer extension services, better nutrient management, contour plowing, improved seed varieties or simple irrigation.
The smallest lymphatic vessels are called lymph capillaries. These vessels are closed at their ends and have very thin walls that allow interstitial fluid to flow into the capillary vessel. Once the fluid enters the lymph capillaries, it is called lymph.Lymph capillaries can be found in most areas of the body with the exceptions of the central nervous system, bone marrow, and non-vascular tissue. Lymphatic capillaries join to form lymphatic vessels. Lymphatic vessels transport lymph to lymph nodes.ymphatic vessels are similar to blood vessels, but they don't carry blood. The fluid transported by lymphatic vessels is called lymph. Lymph is a clear fluid that comes from blood plasma that exits blood vessels at capillary beds.
Lymphatic vessels contain one-way valves to prevent the back flow of lymphatic fluid. The lymph capillaries drain the lymph to larger contractile lymphatics, which have valves as well as smooth muscle walls. These are called the collecting lymphatics. It is interesting to know that unlike blood circulatory system, your lymphatic system does not possess any pumping organ for the movement of lymph through its network of channels. Tiny one way valves push the lymph from node to node.
