All have NO LYMPHATICS, except

LYMPHATIC VESSELS AND CAPILLRIES - When circulating blood reaches the capillaries, pa of its fluid content passes into the surrounding tissues as tissue fluid. Most of this fluid re-enters the capillaries at their venous ends. Some of it is, however, returned to the circulation through a separate system of lymphatic vessels (usually called lymphatics). The fluid passing through the lymphatic vessels is called lymph. The smallest lymphatic (or lymph) vessels are lymphatic capillaries that join together to form larger lymphatic vessels. The largest lymphatic vessel in the body is the thoracic duct. It drains lymph from the greater pa of the body. The thoracic duct ends by joining the left subclan vein at its junction with the internal jugular vein. On the right side there is the right lymphatic duct that has a similar termination. Lymph capillaries - They are present in most tissues of the body. They are absent in avascular tissues (e.g., the cornea, hair, nails); in the splenic pulp; and in the bone marrow. It has been held that lymphatics are not present in nervous tissue, but we now know that some vessels are present.
