The Respiratory System

Function: To supply oxygen to all the parts of your body.


Main Organs: The airways, lungs, blood vessels, and muscles that are attached allow you to breath


Inside your body oxygen allows all your cells to make energy so your body can function properly. Breathing is the main function in the respiratory system. Everyone has two lungs that are surrounded by a rib cage and they rest on a dome shaped muscle called the diaphragm. Every time you take a breath, the diaphragm contracts and moves down, and your rib cage expands. When the air travels into your lungs, air moves into small passages called bronchial tubes. Then the alveoli are tiny sacs surrounded by blood vessels called capillaris. Oxygen then travels to your bloodstream. When your lungs take oxygen in they send carbon dioxide out.
