My Lungs

My Lungs

My lungs are part of a system that keeps me alive. My lungs help my body get the oxygen it needs.

Oxygen comes from the air I breathe. My lungs pull oxygen from the air with each breath.

Each breath comes into my nose or mouth first. My nose and throat warm up and clean the air. Tiny hairs in my nose and throat do the cleaning.

The air moves down my throat into my two lungs. It moves through tubes in my lungs that branch like trees.

The tubes end in tiny sacs that look like bunches of grapes. The tiny sacs are like balloons.
