  • Dear TEACHER, I did not mean to put what the correct answers were. They are supposed to fly in after the class answers the question.

Resp. system

  1. 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 and removing carbon dioxide and water from the body.
  2. 2. Organs of the system and their functions:• Nose and mouth: oxygen enters.• Trachea(wind pipe): tube that enters chest cavity and splits into 2 smaller tubes called bronchi.• Epiglottis: flap that opens to let air in ; keeps food out.• Lungs: bronchial tubes that divide into smaller tubes which connect to tiny sacs called alveoli.• Diaphragm: a muscle that pumps carbon dioxide out of lungs and pulls oxygen into the lungs.
  3. 3. Connections to other systems• Rib cage protects the lungs - Skeletal system• Diaphragm, a muscle - Muscular system• Epiglottis keeps food out - Digestion system• Lungs, where oxygen is picked up by blood - Circulatory system
  4. 4. Possible diseases that can affect this system:• Asthma – a disorder that is controllable, but not curable that causes airways of lungs to swollen and narrow bleeding to wheezing, 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 bronchial tubes becomes inflamed or infected.• Lung cancer - occurs when this uncontrolled cell growth begins in one or both lungs.• Common Cold is an infection of the nose, nasal passages, and the throat.
  5. 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. 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. 7. What systems would not function without the respiratory system?• Digestive system: muscles can not function without oxygen ; no way to push down food.• Cardiovascular: the heart can not pump with out oxygen and deliver blood to the body.
  8. 8. Interesting Facts about the respiratory system…..• The left lung is smaller than the right lung to provide space for the heart.• The sneezing rate/speed record is 165 km per hour.• The breathing rate is faster in children and woman than in men.
