1. The Respiratory System

2. Primary Functions of respiratory system
The Respiratory System supplies the blood with oxygen so that the blood can deliver the oxygen to all parts of the body.
And also removes carbon dioxide waste that cells produce.

3. Respiratory System Structure
Mouth: Passes air through
Trachea: Main tube connecting nose/mouth to lungs
Lungs: Main organ of the Respiratory System
Capillaries: Blood vessels that are imbedded in the walls of the alveoli. While in the capillaries the blood discharges carbon dioxide into the alveoli and takes up oxygen from the air in the alveoli.

4. Respiratory System Structure
Alveoli: Tiny air sacs that do the oxidation and the exhale of carbon dioxide
Bronchi: Two tube inside of lungs that air passes through to the bronchioles
Bronchioles: Small branching out tubes divided into alveoli

5. How The Respiratory System Works
Air that flows from the mouth travels through through the pharynx and moves down to the trachea. Then the air moves to the bronchi tubes as they enter the lungs. Once the air gets in the lungs, the air enters separate branches called the bronchiole. Carbon dioxide passes from the blood into the alveoli and is then exhaled. Once in your lungs oxygen travels from your lungs through the blood system to the cells in all parts of your body. Cells use the oxygen as fuel and give off carbon dioxide as waste gas. The waste gas is carried by the blood system back to the lungs to be exhaled.

6. How To Keep Your Respiratory System Healthy
Try To Avoid:
- Smoking
- Being around a smoker
- Inhaling other chemicals and drugs
- Being around dusty or thick polluted air
What To Do:
