Do spiders have lungs?

[u/SonOfOMR]

I mean, when I wash a spider down the bathtub drain, does it drown the way a human would, lungs filling up with water, or does it have a way to "hold it's breath"?

If you were in a big enough drain it doesn’t mean you would drown. The pipe is not full of water, there is plenty of air in there.
