The lachrymal duct (also spelled lacrimal duct) is a small channel that drains tears from the eye into the nasal cavity. Imagine it as a tiny water slide for your tears. These ducts prevent tears from constantly overflowing onto your cheeks. When you cry a lot, that's why your nose gets runny – the lachrymal ducts are working overtime. They're essential for keeping your eyes clear and comfortable💧.
