From the benefits of ear wax to the origin of your belly button and the reasons for a stuffy nose, The Doctors brings you the facts about your body's orifices.

The body's largest orifice serves many purposes; it allows us to speak, breathe and kiss, but its most important function is as a portal for the first phase of digestion and the beginning of our gastrointestinal track. While eating, we chew and produce saliva, which releases enzymes to break down food and ready it for the next phase of digestion.
Our belly button originates as the base of the umbilical cord, which has a vein and two arteries to nourish a fetus in the womb. Once a baby is born, the umbilical cord falls off, leaving scar tissue behind to create an "innie" or sometimes an "outie", which results from extra scar tissue.

These nose holes are nothing to sneeze at! Our nostrils are the first area where air enters our bodies, and they filter out pollen, moisture and dirt.
Routine ear, nose and throat (ENT) evaluations are essential, and Dr. Ordon examines an audience member's nose, nasal passages and vocal chords. If you experience frequent nosebleeds, runny nose and congestion, make sure to consult your doctor about getting an ENT exam.
