3 Lesson 9.1 Functions and Anatomy of the Respiratory System Chapter 9: The Respiratory System

4 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. the nose the nasal cavity the pharynx the larynx the trachea the bronchi the lungs Anatomy of the Respiratory System

5 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Anatomy of the Respiratory System

6 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. the nose –nares the nasal cavity –conchae –the palate –the sinuses Anatomy of the Respiratory System

7 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. the pharynx –tonsils the larynx –epiglottis the trachea –C rings Anatomy of the Respiratory System

8 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. the bronchi –primary bronchi –bronchioles –the alveoli surfactant pores of Kohn –the alveolar capillary membrane Anatomy of the Respiratory System

9 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. the lungs –mediastinum –apex –pleural sac parietal pleura visceral pleura Anatomy of the Respiratory System

10 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. The Upper Respiratory Tract

11 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Match these words with 1–4 below: surfactant, apex, epiglottis, conchae. 1. lungs 2. larynx 3. nasal cavity 4. alveoli Review and Assessment

12 Lesson 9.2 Respiration: Mechanics and Control Chapter 9: The Respiratory System

13 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. respiration nonrespiratory air maneuvers control of breathing lung volume Respiration: Mechanics and Control

14 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. also known as breathing air always moves from a higher pressure area to a lower pressure area four key tasks involved in respiration –pulmonary ventilation –external respiration –respiratory gas transport –internal respiration Respiration

15 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Boyle’s law –as the volume of a gas increases, the pressure of the gas decreases Respiration

16 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. inspiration (inhalation) –diaphragm and intercostal muscles contract –thoracic cavity expands expiration (exhalation) –diaphragm and intercostal muscles relax –thoracic cavity shrinks Respiration

17 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Respiration

18 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Nonrespiratory Air Maneuvers

19 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. neural factors –pons and medulla oblongata chemical factors –central chemoreceptors –peripheral chemoreceptors –mechanoreceptors Control of Breathing

20 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Control of Breathing

21 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. static –air volume in lungs dynamic –air volume in lungs based on time Lung Volume

22 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. tidal volume vital capacity residual volume functional residual capacity inspiratory reserve volume expiratory reserve volume total lung capacity Static Lung Volume

23 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. forced expiratory volume in one second forced expiratory volume in one second/forced vital capacity Dynamic Lung Volume

24 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. True or False? 1. The pons and medulla control breathing. 2. Static lung volume involves time. 3. Muscles contract in inspiration. 4. Larger gas volume, higher pressure. 5. Gas moves from low to high pressure. Review and Assessment

25 Lesson 9.3 Respiratory Disorders and Diseases Chapter 9: The Respiratory System

26 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. upper respiratory tract illnesses lower respiratory tract illnesses chronic obstructive pulmonary diseases asthma lung cancer Respiratory Disorders and Diseases

27 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Upper Respiratory Tract Illnesses

28 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. avoiding URIs –cover when sneezing and coughing –wash hands –don’t touch hands to eyes, nose, mouth influenza –vaccine Upper Respiratory Tract Illnesses icyimage/Shutterstock.com

29 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. acute bronchitis –inflammation pneumonia –infection tuberculosis –infection Lower Respiratory Tract Illnesses

30 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. causes –smoking living with COPD –stop smoking –purse-lipped breathing Chronic Obstructive Pulmonary Diseases

31 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. emphysema –decreased lung surface area –pink puffers chronic bronchitis –inflammation obstructs airways –blue bloaters Chronic Obstructive Pulmonary Diseases

32 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. asthma attack –inflamed and narrowed airways –bronchospasms –caused by allergens or irritants –treatment relaxes muscles to expand airways Asthma xavier gallego morel/Shutterstock.com

33 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. more deaths from lung cancer than other cancers non-small cell lung cancer –more common lung cancer small cell lung cancer –less common lung cancer Lung Cancer

34 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Fill in the blanks with: small cell, bronchospasms, decreased lung surface area, or infection. 1. An asthma attack includes _______________. 2. A symptom of emphysema is _______________. 3. The more common lung cancer is _______________. 4. Tuberculosis is caused by _______________. Review and Assessment
