 Gross Science is produced by WGBH for PBS Digital Studios ||||| Snot, you perplexing green goop, you smell-stopping slime that oozes forth from my face, what secrets do you hide? What message, O poor sick body, who do you telegraph me through this globby gak? 
  
 As we enter the depths of winter, a pair of videos from PBS Digital Studios’ Reactions and Gross Science have offered to enlighten us on the nature of nose nasties. So now, sit back as we sing the song of snot.

 The usual snot runs clear, acting as a lubricant and the body’s first line of defense against viral and bacterial invaders. The nose’s so-called goblet cells produce proteins called mucins that link into chains, with sugars at their tips to help absorb water. Mucous is 95 percent water, in fact, while crusty boogers are simply snot sans moisture. A healthy individual makes a half a cup of snot per day, and swallows almost all of it. 
  
 Bacteria-destroyling enzymes called lysozymes and white blood cell-beckoning antibodies live inside the goop to kill any intruders. But first line defenses can fail. 
  
 A healthy individual makes a half a cup of snot per day, and swallows almost all of it. 
  
 An allergic response might cause white blood cells to release histamines, signaling blood flow to the nose and causing your snot to run. An infection also sends blood to the nose, causing inflammation and a stuffy, congested feeling. Mucus could even pool in the sinus cavities, the air pockets in your face’s bone structure, building up pressure and triggering headaches.

 But snot doesn’t just get in the way when you’re sick—it plays an active role in helping you get better. First, the slime helps to trap and fight teeny terrors. White blood cells might join the fight, thickening the mucus and turning it white and opaque. And if your mucus has turned green, that means immune cells called neutrophils have released myeloperoxidase, an acid-producing enzyme that aids in bacterial slaughter. If your sick snot is red, that’s blood, so stop picking or blowing your nose for a while. 
  
 Different medicines loosen up your nose’s mucus in different ways. Decongestants squeeze blood vessels in the nose, reducing inflammation by restricting the blood supply. Anithistamines, meanwhile, block the body’s histamines that signal for a runny response. 
  
 Incredible snot, who knew you were so wonderful. Thank you for keeping me safe from the meanest of microbes, and keep on stuffing my nose so that I may stay healthy.

 It's peak cold and flu season, and mucus is making many of our lives miserable. But despite being a little icky, phlegm gets a bad rap. This germ-fighting goo contains cells and chemical compounds that help us power through a cold. You can also think of mucus as a traffic light for your health - what turns up in our used tissues can be a useful clue about the inner workings of our immune systems.

Output:
There's a lot of snot oozing out of people's nostrils this time of year, but did you know we produce half a cup a day just when we are healthy, and unwittingly swallow almost all of it? PBS Digital Studios has published two "gross science" videos on YouTube about snot, and the takeaway is that, as gross as it is, snot is also crucial to helping us stay healthy. In fact, the presenter goes so far as to call it "truly terrific stuff." Among the tidbits: mucus is 95% water, while crusty boogers are just dehydrated versions. Mucus forms all over our bodies, even in our genitals, to keep delicate body tissue moist and trap invading particles that might do us harm. Our bodies produce more mucus to flush out those pathogens and also send in little immune cell armies to wage battle. And congestion isn't actually from an enormous buildup of snot, but rather nasal inflammation blocking those airways. If your snot is green, your body is in full-on bacteria slaughter mode, reports Gizmodo, while red means blood, so stop blowing and picking your nose for a bit. (Like snot, ear wax is beneficial.)
