What happens with dust when we breathe it in, where does it go?

Question

We breathe in dust all the time; dirt in the air, dead skin cells, smog, sawdust, etc. where does this all eventually go? It can’t physically all just build up or we would eventually suffocate right?

Answer 1

Some dust just collects in your lungs and can cause serious health problems. Silicosis (https://en.wikipedia.org/wiki/Silicosis) is caused by regularly breathing in concrete/ceramic/glass dust.
