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.
Lymph enters vessels known as the subclavian veins, which transport it back to the circulatory system. Afferent vessels transport fluid into the lymph nodes, while efferent vessels carry filtered lymph away from the lymph nodes. White blood cells called lymphocytes are a major part of the lymphatic system.Lymph nodes may become swollen when a person gets sick.fter the lymph has been filtered by the lymph nodes, it passes into the efferent vessels. These lymph vessels come together in large groups sometimes referred to as a lymph trunk. They drain the filtered fluid into one of two lymph ducts, which are very large lymphatic vessels.
