lacrimal canaliculi, one in each eyelid, commence at minute orifices, termed puncta lacrimalia (or lacrimal punctum, or lacrimal point), on the summits of the papillae lacrimales, seen on the margins of the lids at the lateral extremity of the lacus lacrimalis. There are two lacrimal puncta in the medial (inside) portion of each eye.
Together, they function to collect tears produced by the lacrimal glands. The fluid is conveyed to the
lacrimal sac, and thence via the nasolacrimal ductto the inner nose.
