RespiratorySystemand Smoking Mr.McCarthy Rogich MS
This Presentation Will Cover: • Respiratory System Definitions • Label Respiratory System • Breathtaking Facts • Respiratory System Diseases • Types of Tobacco Products • Smokin’ Hot Facts • Parts of Cigarette Smoke • Smoking-Related Problems • Warning Labels • Quitting Smoking
DEFINITIONS: • RESPIRATION: The process by which your body takes in oxygen and releases carbon dioxide
DEFINITIONS: • CELLULAR RESPIRATION: The process by which every cell of your body takes in oxygen and releases carbon dioxide
DEFINITIONS: • LUNGS: Two breathing organs in the chest which transport oxygen into the blood and remove carbon dioxide
Real lungs look like this: Think smoking is good for your lungs?
DEFINITIONS: • PLEURA: Slimy thin covering that protects and cushions the lungs and makes it easier to breathe
DEFINITIONS: • DIAPHRAGM: Dome-shaped muscle that separates the chest cavity from the abdomen
DEFINITIONS: • NASAL CAVITY: Space behind the nose which warms and moistens the air you inhale
DEFINITIONS: • SINUSES: Air-filled pockets located within the bones of the face and around the nasal cavity
Sometimes, the sinuses and nasal cavity are affected by allergies and infections
DEFINITIONS: • PHARYNX: The proper name for your throat
DEFINITIONS: • LARYNX: Upper part of the respiratory system which contains the vocal cords
The Larynx is sometimes called the “Voice Box” or Adam’s Apple
The size and shape of your larynx and vocal cords create your unique voice
DEFINITIONS: TWO BIG TUBES IN YOUR NECK: • TRACHEA: Front tube which leads to the lungs • ESOPHAGUS: Back tube which leads to the stomach
DEFINITIONS: • EPIGLOTTIS: Structure which prevents food from entering the trachea when you swallow
DEFINITIONS: • BRONCHI: Branches of the trachea through which air enters the lungs
DEFINITIONS: • MUCOUS: A thick, slippery substance made inside your lungs to collect dirt, dust, and bacteria
DEFINITIONS: • CILIA: Microscopic, tiny hair-like projections which line the bronchi and sweep dust, dirt, bacteria and mucous out of the lungs
Dust and dirt stick to the mucous, then the cilia sweep the junk out of your lungs
Guess what cigarette smoking does to the cilia? Smoking damages the cilia, making infections like bronchitis more common
DEFINITIONS: • BRONCHIOLES: Smaller and smaller branches of the bronchi
DEFINITIONS: • ALVEOLI: Billions of tiny microscopic air sacs in the lungs
ALVEOLI: This is where oxygen enters the red blood cells and carbon dioxide leaves the blood

Without LookingAt Your Notes…. How many parts of the Respiratory System can you name?
Respiratory System Label Nose and Nasal Cavity 1. Mouth 2. Pharynx or Throat 3. Larynx or Voice Box 4. Trachea or Windpipe 5. Lung 6. Left branch of Bronchi Right branch of Bronchi 7. 8. 9. Bronchioles Alveoli 10. Diaphragm 11.
Can you list a few things we did not label? • Sinuses: Air-filled pockets located within the bones of the face • Epiglottis: Prevents food from going down wrong pipe • Pleura: Slimy membrane or coating • Esophagus: Tube to stomach • Cilia: Hair-like projections which line the bronchi
Breathtaking Fact #1 • You breathe about 5,000 to 10,000 times per DAY. • That’s about 9 to 20 times every MINUTE.
Breathtaking Fact #2 SNEEZING the body's way of removing an irritant from the sensitive mucous membranes of the nose.
Breathtaking Fact #3 You have over 600 million ALVEOLI in your lungs. If stretched out, their surface area would cover a whole tennis court!
Breathtaking Fact #4 HICCUPS are sudden movements of the diaphragm. They are involuntary. There are many causes of hiccups: • The diaphragm may get irritated • You may have eaten too fast • Some substance in the blood could even have brought on the hiccups.
By The Way: The strange noise we make when we hiccup is partly caused by the pushed air hitting the epiglottis and vocal cords, which do not expect the hiccup!
Breathtaking Fact #5 Breathing in HELIUM makes your voice change! Helium is much lighter than air. Because of this, the speed (and wavelength) of sound is much higher in helium.
