Do you know what tonsil stones are? Technically, they're called tonsilloliths, and are made up of bacteria, dead cells, mucus, and other junk that can collect in the grooves of the tonsils. This buildup can happen due to stress, but the most common reason is tonsillitis (inflammation of the tonsils). The tonsils are supposed to trap bacteria and foreign stuff, but when they are inflamed, they are puffier. This puffiness can cause grooves in the tonsils to close up, which means any bacteria or foreign stuff would get trapped, until it's big enough to poke out of the groove. That's when you see them and get grossed out!
Did you know your organs can be covered in "icing"? This disease happens when an organ's outer membrane is inflamed and can grow a white coating. It most often affects spleens, but can happen to the liver and heart, too. Just keep that icing on cake, where it belongs - and away from my spleen!
