Why do we need to breathe?

Oxygen is essential for life. Normal air contains 21\% oxygen, which we breathe into our lungs so it can enter our bloodstream to help with the proper functioning of our tissues and organs. We also breathe as a way to expel carbon dioxide gas, which is a type of waste our bodies produce.

How do we breathe?

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

How do we breathe short answer?

The diaphragm (a muscle under the lungs) moves down. This makes more space for the lungs which fill up with air from the mouth and nose. The air moves through tubes in the lungs to tiny air sacs called alveoli. Oxygen passes from these into the blood, which carries the oxygen to all the cells in the body.
