Cardiology (Cardiovascular Disease)

The nose is the body's first line of defense against airborne invaders, so it should come as no surprise that there are colonies of germs living inside the nasal cavity. For the most part, bacteria and debris don't get very far into the body because there is a very efficient protective mechanism inside the nose. Tiny hairs called cilia move ever so slightly to snare and trap what they can in mucous-coated hairs, keeping anything from reaching the breathing passages and gaining access to the bloodstream.
