1. What is the respiratory system and what does it do?The respiratory system is a body system that is responsible for performing thetask of getting oxygen into the body andremoving carbon dioxide and waterfrom the body.

2. Organs of the system and theirfunctions: Nose and mouth: oxygen enters. Trachea(wind pipe): tube that enters chest cavity andsplits into 2 smaller tubes called bronchi. Epiglottis: flap that opens to let air in ; keeps foodout. Lungs: bronchial tubes that divide into smaller tubeswhich connect to tiny sacs called alveoli. Diaphragm: a muscle that pumps carbon dioxide outof lungs and pulls oxygen into the lungs. 3. Connections to other systems Rib cage protects the lungs - Skeletalsystem Diaphragm, a muscle - Muscularsystem Epiglottis keeps food out - Digestionsystem Lungs, where oxygen is picked up byblood - Circulatory system 4. Possible diseases that can affect thissystem: Asthma a disorder that is controllable, but not curable thatcauses airways of lungs to swollen and narrow bleeding towheezing, shortness of breath, chest tightness, and coughing. Pneumonia a breathing condition infection of the lungs,that creates a fluid and mucus that blocks the alveoli. Bronchitis the condition in which the lining of the bronchialtubes becomes inflamed or infected. Lung cancer - occurs when this uncontrolled cell growthbegins in one or both lungs. Common Cold is an infection of the nose, nasal passages, andthe throat. 5. The steps of how the system works when inhaling:1) The diaphragm contracts and flattens out so lungs have more room to grow larger as they fill up with air.2) At the same time, we inhale air through mouth and nose3) Air goes through the wind pipe or trachea.4) On the way down the windpipe, tiny hairs called cilia move gently to keep mucus and dirt out of the lungs.5) Air goes through the series of branches in your lungs, through the bronchi and bronchioles.6) Air ends up in the alveoli which fills up with air, and then the lungs get bigger. 6. The steps of how the system works when exhaling:1) The diaphragm relaxes and moves up, pushing air out of the lungs.2) Rib muscles become relaxed, and your ribs move in again, creating a small space in your chest.3) By now, the cells have used the oxygen they need, and your blood is carrying carbon dioxide and other wastes that must leave your body.4) The blood comes back through the blood vessels, or capillaries and wastes enter the alveoli.5) Then you breathe out the carbon dioxide in the reverse order of how they came in the air goes through the bronchioles, out the bronchi, out of the trachea, and finally out through the mouth and nose. 7. What systems would not functionwithout the respiratory system? Digestive system: muscles can notfunction without oxygen ; no wayto push down food. Cardiovascular: the heart can notpump with out oxygen anddeliver blood to the body. 8. Interesting Facts about the respiratorysystem.. The left lung is smaller than theright lung to provide space forthe heart. The sneezing rate/speed record is165 km per hour. The breathing rate is faster inchildren and woman than in men. 9.
