Stomata - an opening, basically.

You may recall stomata from biology class. Plants have tiny, small openings or slits in the epidermis of their leaves and stems that allow the exchange of gases - it's how plants breathe. A stomata can also be a mouth or artificial opening. I recently came across the word again while taking a first aid course - that is, some people have a stomata installed for breathing. You can perform CPR on the stoma. Huh!
