lymphatic ducts  channels for conducting lymph.

lymphatic duct, left  thoracic d.

lymphatic duct, right  a vessel draining lymph from the upper right side of the body, receiving lymph from the right subclavian, jugular, and mediastinal trunks when those vessels do not open independently into the right brachiocephalic vein.

mesonephric duct  an embryonic duct of the mesonephros, which in the male develops into the epididymis, ductus deferens and its ampulla, seminal vesicles, and ejaculatory duct and in the female is largely obliterated.

duct of Müller , müllerian duct paramesonephric d.

nasolacrimal duct  the canal conveying the tears from the lacrimal sac to the inferior meatus of the nose.

papillary duct  a wide terminal tubule in the renal pyramid, formed by union of several straight collecting tubules and emptying into the renal pelvis.

paramesonephric duct  either of the paired embryonic ducts developing into the uterine tubes, uterus, and vagina in the female and becoming largely obliterated in the male.
