EXERCISE 7 Respiratory System Mechanics O B J E C T I V E S 1. To explain how the respiratory and circulatory systems work together to enable gas exchange among the lungs‚ blood‚ and body tissues 2. To define respiration‚ ventilation‚ alveoli‚ diaphragm‚ inspiration‚ expiration‚ and partial pressure 3. To explain the differences between tidal volume‚ inspiratory reserve volume‚ expiratory reserve volume‚ vital capacity‚ residual volume‚ total lung capacity‚ forced vital capacity‚ forced expiratory

Respiratory Volumes Activity 2: Measuring Normal Respiratory Volumes 1. Minute respiratory volume: 7‚500 ml 2. Judging from the trace you generated‚ inspiration took place over how many seconds? 2 seconds 3. Expiration took place over how many seconds? 2 seconds 4. Does the duration of inspiration or expiration vary during ERV or FVC? Yes Activity 3: Effect of Restricted Air Flow on Respiratory Volumes 5. How does this set of data compare to the data you recorded for Activity

Exercise 7 Review Sheet Definitions/Explanations: Respiration: The entire process of gas exchange in the body; it includes each of the following: 1. Pulmonary Ventilation (AKA breathing): The follow of air into and out of the lungs. The result of muscle contraction of the diaphragm. Ventilation consists of two parts: a. Inspiration: The process that occurs when atmospheric gas is drawn into the lungs by way of contraction of the diaphragm which causes expansion of the thoracic

Moves air to and from area of gas exchange C. Protects gas exchange surfaces D. Sound production E. Provides olfactory sensations to the CNS F. Capillaries in lungs produce angiotensin converting enzyme (ACE) II. 4 Respiratory processes A. Pulmonary ventilation (breathing) 1. Move air in and out of lungs B. External

activity are you simulating when you click the ERV button? What additional muscles are used? Maximal exhalation; internal intercostal and abdominal wall muscles What does the pump rate simulate? The number of beats per minute (BPM) stimulates respiratory rate How did changing the radius effect FEV (%)? FEV decreased in response to decrease in radius What effect does the addition of surfactant have on the airflow? AIrflow increases because resistance is reduced. Why does surfactant affect
