from what i know about helium; it is lighter than air or the oxygen we breathe so it sits higher in your lungs. Therefore when you exhale it passes through your vocal cords faster which is why your voice is a higher pitch. If you breathe too much Helium in you will become light headed because you aren't getting the oxygen your cells need. An example of a different gas is xenon which is denser and heavier than air. Therefore when you breathe it in it sits at the bottom of your lungs and takes longer to pass through your vocal cords and makes your voice much deeper. It's pretty interesting however xenon is very expensive.

Can something breathe helium?
It depends on what you mean. We can breathe helium without any ill effects as long as we get enough oxygen. However, nothing could breathe and use helium as we breathe and use oxygen because helium is inert. Unlike oxygen, which is highly reactive, helium does not participate in chemical reactions, so it could not serve an organism any purpose.
