@instituteofhumananatomy: What is actually inside your nose? A built-in air-conditioning system. But first, how well do you really know your own anatomy? Download the new IOHA Daily app, our free one-minute anatomy game that just launched. Spin a real 3D structure, guess the body part, and learn something new every day. Get it now on the App Store and Google Play, or play at iohadaily.com. Now, the nose. Inside the nasal cavity are curled shelves of bone called the conchae, or turbinates, and the air passes between them. They massively increase the surface area, and their lining has a very rich network of blood vessels. As air moves through, the blood supply warms it, the moist lining humidifies it, and mucus and tiny hairs filter out dust and debris, all before it reaches your lungs. That same rich blood supply is also why noses bleed so easily.
