Lymphatic capillary 毛细淋巴管
Begin blindly
The wall posed of a single layer of overlapping endothelial cells
They are numerous and works
Be fund in all tissue ans of the body except(abscent in) the central nervous system, the eyeball, the internal ear, the epidermis of the skin, the cartilage, and the bone
Lymphatic vessel 淋巴管
Have valves that give them a beaded appearance
Two sets
Superficial set: lie in the superficial fascia
Deep set: run with blood vessels and nerves
Passes through at least one lymph node and often several

★ Thoracic duct 胸导管
Begins in front of lower border of T12 as a dilated sac, the cisterna chyli 乳糜池, which formed by joining of left and right lumbar trunks and intestinal trunk
Enter thoracic cavity by passing through the aortic hiatus of the diaphragm and ascends along on the front of the vertebral column, between thoracic aorta and azygos vein
Travels upward, veering to the left at the level of T5
