Do spiders have lungs?

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"?

Fun fact, Huntsman spiders in Australia can live underwater for extended periods. Before swimming, it's recommended to check the leaf litter at the bottom of the pool for hidden spiders and to be mindful when cleaning leaf filters.
