Warm Up • Respiratory System Reading and Questions Respiratory System Functions of the Respiratory System • • • • Breathing process Supplies blood with oxygen (inhale) Remove carbon dioxide from cells (exhale) Enable speech production Structures of Respiratory System • upper respiratory tract – nose, mouth, pharynx, epiglottis, larynx and trachea • lower respiratory tract – bronchial tree and lungs Frayer Model “competition” • With your group, you will complete sets of Frayer models using the textbook and a handout • You will have 15 minutes per page • At the end of time, your group with get points – Completing all parts of each Frayer model = 1 point – Having correct information in each Frayer model = 2 points – Group working together = 2 points Characteristics • You will not find a sentence that says…. “The characteristics are ….” A characteristics is something that describes something else (normally an adjective) Frayer Models Respiratory System Oxygen Mouth, Nose & Nasal Cavity Nasal Mucus & Cilia Use Handout page 35 And Textbook 40B Respiratory System Definition: the body system that’s function is to get oxygen from the environment and remove carbon dioxide from your body Characteristics: very important to human life Importance: brings oxygen into the body and humans cannot live without oxygen Parts: mouth, nose, nasal cavity, Trachea, Epiglottis, lungs Oxygen Definition: an important gas human’s need to live Characteristics: essential to human life, taken from the air around us Importance: without oxygen you would die Non-Example: carbon Dioxide Mouth, Nose and Nasal Cavity Definition: the way air enters the respiratory system; the first place air goes in the body Characteristics: on your head Importance: we need them so that we can inhale oxygen Non-Example: Ear Nasal Mucus and Cilia Definition: mucus = a sticky liquid, Cilia = little nose hairs Characteristics: inside your nose Importance: help trap dirt and germs Picture Frayer Models • • • • Trachea (35) Epiglottis (35) Pharynx Larynx Trachea Definiton: the tube that connects the upper respiratory system (mouth & nose) to lungs Job: separates the 2 sides of the lungs Made of cartilage tissue Epiglottis Definition: a flap of skin that covers the trachea, in the back of your throat above tounge Why is it important? Stops food or liquid from getting into your lungs Job: Stops food or liquid from getting into your lungs Picture Pharynx Definition: area behind the nose that leads to the throat – controls the amount of air that gets into your lungs. Picture: Why do you think it is important? to make sure too much air doesn’t go down into your lungs and pop them Larynx Definition: also called voicebox, contains cords that vibrate to produce sound Characteristic: at the bottom of the Pharynx Importance: Without a Larynx you would not be able to talk Warm Up – put HW on desk Copy sentences and fill in the blanks. The Respiratory System is important because it controls ___________, which humans must do to stay alive. The ____________ is the part of the Respiratory System that stops food from getting into our lungs. Warm Up The Respiratory System is important because it controls BREATHING, which humans must do to stay alive. The EPIGLOTTS is the part of the Respiratory System that stops food from getting into our lungs. Frayer Models • • • • Lungs (39) Bronchial Tubes (40B and 39) Alveoli (39 and 40B) Diaphragm (40B) • cross out picture and write “JOB” Cross out non-example and write location Lungs Definition: the main organ of the respiratory system, most complicated Look like: a tree Number: a human has a pair a lungs (2)- one on each side of heart Lungs trachea Bronchial Tubes Definition: 2 braches/tubes of the lungs Characteristics: carry air into each lung, have thousands of little branches or “twigs” Picture: Location- inside the lungs Alveoli Definition: small sacs that fill with air when we breath in. Characteristic: very small, like a balloon Job: Put oxygen into blood and take out carbon dioxide Location: at the end of each bronchial tube/twig Diaphragm Definition: a large muscle that stretches across the floor of the thoracic cavity (lungs) Characteristics: very big, strong, important Importance: allows you to breathe in and out How it works: diaphragm contracts (get flat) = air flows in lungs, inhale • diaphragm expands (puffs up) = air flows out of lungs, exhale – http://www.youtube.com/watch?v=hp-gCvW8PRY • http://www.nhlbi.nih.gov/health/healthtopics/topics/hlw/whathappens.html The Path Oxygen takes through the body • Now that you have all of the definitions, you must know the order/path oxygen takes throughout the body • Diagram The Path Oxygen Take Throughout the Body 1. 2. 3. 4. 5. 6. 7. Mouth / Nose Pharynx Larynx Trachea Bronchial Tubes Lungs Alveoli Mouth / Nose The only 2 places that oxygen can enter the body Nose contains cilia and mucus to trap dirt and germs 2. Pharynx Behind nose, leads to throat - Controls the amount of air that enters the lungs 3. Larynx Below Pharynx Also called Voice box Produces sounds, uses oxygen to vibrate cords and make noises 4. Trachea • AKA Windpipe • Covered by the Epiglottis • Tube that carries oxygen towards the lungs 5. Bronchial Tubes 2 braches/tubes that carry air into each lung Branch out into several more “twigs” 6. Lungs Look like a tree Take oxygen in And carbon dioxide out of the body 7. Alveoli Inside lungs, on the end of the Bronchial Tubes’ twigs Put oxygen into blood Take out carbon dioxide Diagram Glue, Staple or Tape diagram to the back of the foldable Make sure you have written the correct number next to the word After You Read Pg 37 – cross out #7 and 6 Exit Ticket What part of the Respiratory System actually puts oxygen into the blood? What object do our lungs look like?

Trachea Extra credit – Diaphragm Asthma What is it? a condition that affects a person's bronchial tubes/airways. • http://www.lung.org/lungdisease/asthma/becoming-an-advocate/ Asthma There are 3 things that happen to people with Asthma 1. Inflammation of airways, (tubes get smaller) 2. Bronco constriction – tightening of muscles 3. Increase in mucus production All of these things make it harder for oxygen to get through to lungs What causes it? Different people have different triggers — things that set off asthma flare-ups • • • • • • dust mites (tiny bugs that live in dust) mold Pollen Animals perfume, chalk dust, and cigarette smoke Exercise How is it treated? Not every kid's asthma is the same, so there are different medicines for treating it. It's not like curing a sore throat or an earache, when everybody gets the same medicine. Instead, the doctor will think about what causes the asthma flare-ups, how fast the flare-ups happen, and how serious they are. Then he or she will decide on the best kind of treatment. Common Treatment Inhaler – works to open airway How do you help? Help them get into a comfortable sitting position. • Many asthma patients carry not only an inhaler, but a written instruction card as well. An asthma attack can temporarily rob the patient of his ability to speak. • * Help them use the inhaler. An inhaler is designed to deliver a specific dose of asthma medication. The medication relaxes the patient's airways and helps restore normal breathing. • * If it appears that they are not responding to the medication within ten minutes, call an ambulance. And continue to deliver about four puffs of medication every five minutes while waiting for the ambulance. • The medication will help prevent the asthma attack from getting worse even if it doesn't seem to provide immediate relief. • * Stay calm throughout the episode. This will help the patient remain calm as well. If he panics, it will worsen the asthma attack and make it far more difficult for him to breathe. Bill Nye Respiration Exit 1. Why is your right lung bigger than the left? 2. What happens to a person’s airways if they have asthma? 3. What is one thing that can cause asthma?
