Not at the same time. One nostril is more open than the other at all times and they switch about every 7minutes or so. This is to stop the delicate lining drying out too much and becoming irritated.
because the haemoglobin present in our blood has no capacity to absorb nitrogen so the result is that the nitrogen is not absorbed and you breathe out the same amount of nitrogen as you breathed in.......
The same amount you wil just breathe in more often
Through their nostrils, much like other land-based mammals.The same way as any other air-breathing animal does - through their lungs !They breathe through their nostril's, mouths and lungs.
The same way as you. Air goes through the nostril and into the lungs. Then it circulates. Then it comes back from the lungs out through the nostrils.
They both contain the same elements, only different quantities of them.
same thing human nostrils do - direct air into the lungs !
... the same way humans do. With lungs. Through their nose. They can hold their breathe at a walk and trot but at a halt,canter and gallop they have to breathe so NEVER block their noses or they can't breathe because its impossible for them to breathe through their mouths.
The kakapo's nostrils are at the top of its beak, the same as all other birds except the kiwi (which has its nostrils at the end of its beak).
No. The tiny hairs (cilia) in your nostrils collect input as well as output.
Chimps have lungs and breathe just like we do.
Same as humans, they are both mammals. Lungs.
All snakes have all the same organs we do. However they have one lung, and a Jacobson's organ (also found in cats).though their nostrils just like you and me!! they are located on the top of their head above their mouth and below their eyes. try looking up a picture and zoom in on its head and you might see them
