How do we breathe from nose when we eat?

You dont breathe when you swallow.

 

This appears to me to be a significant advantage, especially for herbivores. The ability to chew and not restrict breathing allows for the crushing of the food over extended periods of time.

 

I have unwillingly tried this many times and doing both at the same time leads to (near) choking. I am obviously still alive, so one might claim that "it worked" but I guess this is due to the two processes somehow organising themselves sequentially after a bit of a "bottleneck" (the choking).

Warning: I don't recommend you try this at home!

 

My daughter's pediatrician told me that infants can breathe and swallow at the same time, up to about 6 months of age.

 

I have to be extremely careful, with the COPD. Frequently I have to breathe through my mouth while chewing. It's really tricky to get the air past the food without inhaling something solid.

 

Definitely true. They'd suffocate while breastfeeding otherwise.

 

I'd be more than happy to volunteer as a test subject for that.
