Respiratory system contains many parts that are all important to the system. The major parts are the lungs, the diaphragm, the abdomen, and the windpipe. Some of the smaller connected parts are the nose, the mouth, and the trachea. The lungs are the most important part of the respiratory system. Inside the lungs there are alveoli’s, the bronchus, and the bronchioles. All the parts work together in order to make you breathe.

The respiratory system is important because it helps you breathe. You need oxygen for everything in your body to work. If you couldn’t breathe you wouldn’t be able to talk, sing, cry, laugh, walk, or live. Since we can breathe we can do all this and much more. Your lungs clean up what you breathe in and then you breathe out the bad stuff.

The respiratory system is very complicated. A lot of different parts & muscles move at different times, working together to make you breathe. When your diaphragm pulls down, it not only leaves space for your lungs to expand but also lowers the internal air pressure. You breathe about 20 times in 1 minute. Your lungs contain 1500 miles of airways & over 300 million alveoli. Your muscles squeeze your rib cage & your lungs begin to collapse. Epiglottis flops down to cover the windpipe so that food doesn’t go down the windpipe. At the end of these tubes are millions of tiny bubbles or sacs called alveoli’s. Alveolus’s let oxygen get absorbed into the blood stream. Spread out flap, all the air sacs in the lungs of an adult would cover an area about the third of a tennis court.

Bronchitis is when you have inflammation in the bronchial tubes. It’s harder to breathe, when your lungs get irritated more mucus is produced and you cough a lot. You can get either acute or chronic bronchitis, the most common is acute. Pneumonia is an infection you can get. You can either get it in one or both lungs. This infection creates too much fluid in the lungs and it makes the alveoli’s stop working properly. Pneumonia is a deadly infection.

Questions: 1. What are the main parts of the Respiratory system? 2. What is the epiglottis's job? 3. How many times do you breathe in a minute? 4. How many miles of airways are there in your lungs? 5. Name both types of bronchitis.
