1. Science Starter 1.What are the 4 steps of respiration? 2.What is the difference between expiration and inspiration? 3.What is the difference between obstructive and restrictive lung disorders? 4.How did our asthma simulation yesterday affect cognitive function?

2. Today’s Agenda Science Starter Respiratory System Notes A Case Study in Physiology Plastination, what is it? Exit Quiz **Unit 6 Assessment Tomorrow** Passes will be given today for the field trip Friday

3. Unit 6: RESPIRATORY SYSTEM 6.4 Respiratory Complications

4. Respiration - process of gas exchange 1. Movement of air into lungs 2. Gas exchange between blood and air (external respiration) 3. Gas transport in blood 4. Gas exchange between blood and cells (internal respiration) *Cellular Respiration - oxygen use and CO2 production at a cellular level

6. Organs of the Respiratory System Main organs of the upper and lower respiratory system Pharynx & Larynx have cartilage bands and muscle tissue The Trachea lacks cartilage bands, causing it to be flexible

7. ALVEOLI

8. Asthma Attack A condition in which a person's airways become inflamed, narrow and swell, and produce extra mucus, which makes it difficult to breathe Symptoms Severe wheezing when breathing both in and out Coughing that won't stop Very rapid breathing Chest tightness or pressure

9. Edema A condition characterized by an excess of watery fluid collecting in the cavities or tissues of the body It is a response of the body to inflammation or injury (allergic reaction) Symptoms Shortness of Breath Heavy Limbs Cough

10. Pulmonary Embolism A condition in which one or more arteries in the lungs become blocked by a blood clot (fat or tumor) Symptoms Shortness of Breath Chest Pain Cough Leg pain or swelling Clammy skin or cyanosis

11. A Case Study in Physiology Read through the case study on Barbara (the grandmother) Use the information in your notes and in the document to answer all the questions Some of the questions will need to be answered on a separate sheet of paper If you need to research, feel free! (all info should be there!)

12. Body Worlds Reading Read both side of the paper Highlight any interesting views, opinions, or ideas Write up a short response on a separate sheet of paper to the following questions: 1.Would you want your body or a relative to go through Plastination? 2.Is it a good idea to exhibit Plastinates for the public?

13. Exit Quiz 1.Do you have any dietary restrictions? (vegan, lactose intolerant, etc.) 2.What was the issue with Barbara, why is this dangerous? 3.Why did these issues cause swelling of her legs? 4.When a person has an asthma attack, what is happening inside the lungs?
