Question

What’s happening when you take a deep breath and your belly puffs out (since your lungs are in your chest and your stomach organ is higher up)?

In: Biology

Answer 1

You have a large muscle between where your lungs are and where your digestive organs are which is called the diaphragm. When you take a deep breath it moves down and helps the lungs above it expand which pushes the organs below it out.
