Mucus is a substance that is part of the human body and of most complex living creatures. It is a sticky and slippery substance, thicker than a liquid, which protects tissues in the body, such as in the nose and throat. When you get tested for a virus, the doctor (or other medical practitioner) usually takes a little mucus from the back of your throat.
Mucous is the adjective form of mucus, and is a word not often used.
