Why Can't Humans Breathe Water. Fishes on the other hand have specialized structures called gills that help them breathe in water. Human beings are not built to work that hard to breathe.

Fish also need oxygen to live, but their. Collectively, it made human beings unable to do more than swim and dive underwater for short durations. Human beings are not built to work that hard to breathe.
Before We Elucidate How, It May Help To Understand Why We Can't Breathe In, Say, Water Or Milk.
