Neither blood nor lymphatic vessels are present in the epithelium (excepted for stria vascularis of the inner ear), sclera, cartilage, or intima of blood vessels. The central nervous system is rich in blood vessels but does not contain internal lymphatics. The lymphatic capillaries are usually ...

Lymphatic vessels are composed of lymphatic capillaries. Their wall structures are similar to veins, and there are many valves in them. According to the distribution position of lymphatic vessels, they can be divided into superficial lymphatic vessels a...
Frequently in this location they also border the lobular parenchyma, but no lymphatic vessels have been found within intralobular compartments between blood capillaries and alveoli. The presence and distribution of lymphatic vessels in pulmonary tissue are consistent with an important role for the ...
of the interstitial fluid will not directly be reabsorbed into the blood system, but rather will be collected into the lymphatic capillaries as lymph, and will pass through one or more of the 600–800 draining lymph nodes disseminated throughout the human body, before circulating into the thorac...
Lymphatic vessels are structures that absorb fluid that diffuses from blood vessel capillaries into surrounding tissues. This fluid is directed toward lymph nodes to be filtered and ultimately re-enters blood circulation through veins located near the heart. The smallest lymphatic vessels are called lym...
molecular and metabolic programs accountable for the lymphatic system’s many and essential functions4. The morphology of lymphatic vessels is often uniquely tied with their distinct functions and sizes4. The most basic constituent of the lymphatic vasculature are lymphatic capillaries, which are highly...

The selected molecular markers of capLECs, collecting (collLECs) and valve LECs (vLECs) are shown. From the draining lymph node (LN) the lymph is transported to the next LNs until it reaches the blood circulation. ECs in LYVE1+ lymphatic capillaries have discontinuous “button-like” and ...
