Where do nose boogers come from?
Boogers or mostly known as mucus is made by the same secretions
as your eyes. Ever notice that when you cry or have tears that a
runny nose follows? This is because your eyes, ears and nose are
all conected. The tears can drain into your nose and throat. Your
Sinus cavity can also make this mucus which is why when you have a
sinus infection, your nose gets all congested.
