Fighting Back!!!

In science I learned how the immune system fights off diseases and the types of whit blood cells. Phagocytes are one type that causes inflammation and takes out pathogens taking over. When they were describing this, they did it in video game style and most likely CALL OF DUTY. We have three types of barriers protecting us, skin, digestive, and saliva/mucus. In the skin the pathogens die from sweet or fall off, but in rare occasions they get in and run far away from the whit blood cells. The most commonly one I think is eating and drinking, since the can after all go as far as a small room. The mucus is actually snout. That’s why when you are in a dusty room you sneeze and snout comes out. This snout thing then leads me to a book I read called ELIJAH OF BUXTON. He has a “friend” that has a handkerchief and blows in to it. Elijah on the other hand thinks that’s disgusting and plugs up one nostril and puts force one it and out comes the pathogens and dust. I bet you don’t know how many colonies live on you, say about 3 million!, but don’t worry the cant get in you have layers of died skin protecting you!
What way do you think the pathogens get in the most, skin, digestive, or mucus and snout? I bet it will be hard for you since of all this information on these barriers.

  1. It is sweat not sweet, but you are sweet!
    also it is snot, not snout - that is where your snot come out of.

    They get in through the digestive system, unless you have big areas of burned skin. So don't play with fire.
