Lymphatic Vessels 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.
