When we breath in our chest expands to some extent but I don’t understand how it that possible. Bones can’t expand or anything, so how are we able to “expand them”, make them “longer”?
In: Biology
There is a muscle in your stomach wich pulls on your lungs to make a vacuum in your lungs so it will suck in air this muscle pushes yourother organs in your belly down but it cant go there because there are bones there so it will expand to the front making you “fatter”
There also is another way to breathe it has to do with tiny muscles in your ribs but i dont know how that works
