lol the title sounds wrong, anyways, i know Cilia moves the mucus upward away from the alveoli towards the throat and then apparently its swallowed which helps prevent lung infection. i dont get why its taken up, away from the alveoli only for it to be swallowed again though?? like why take something up only for it to come back down?

When it's swallowed, it goes down the throat to the stomach not back into the lungs.

It goes away from the lungs up to the throat, and then you swallow it down to your stomach, where it's very acidic and kills the germs.

The pH of the acid in the stomach is high enough to kill the bacteria that could otherwise cause infection. Bacteria is trapped by mucus, wafted up to the throat and swallowed to prevent them causing a lung infection and reducing the efficiency of gas exchange.
