The contraction of which of the following muscles will increase the thoracic cavity volume during inspiration? You correctly answered: c. he external intercostals 3. At the beginning of inspiration, the You correctly answered: b. thoracic cavity volume increases. 4. At the beginning of expiration, the You correctly answered: a. pressure in the thoracic cavity increases. 5. A tidal volume refers to the You correctly answered: b. amount of air inspired and then expired with each breath under resting conditions. 010/24/12 page 1 Experiment Results Predict Question: Predict Question: Lung diseases are often classified as obstructive or restrictive.
An obstructive disease affects airflow, and a restrictive disease usually reduces volumes and capacities. Although they are not diagnostic, pulmonary function tests such as forced expiratory volume (FEV1) can help a clinician determine the difference between obstructive and restrictive diseases. Specifically, an FEV1 is the forced volume expired in 1 second. In obstructive diseases such as chronic bronchitis and asthma, airway radius is decreased. Thus, FEV1 will Your answer : a. decrease proportionately. Stop & Think Questions:
Which muscles contract during quiet expiration? You correctly answered: d. None of these muscles contract during quiet expiration. 6. Minute ventilation is the amount of air that flows into and then out of the lungs in a minute. Minute ventilation (ml/min) = TV (ml/breath) x BPM (breaths/min).
The Essay on Chronic Obstructive Pulmonary Disease 2
Chronic Obstructive Pulmonary Disease (COPD) or also known as Chronic Bronchitis or Emphysema is a disease that happens in the lungs of people who smoke. It blocks the airflow to the lungs with black tar / black carbon. Some symptoms are excessive coughing and continuously out of breath. To ease the symptoms you could you use inhalers, steroids, antibiotics or just more oxygen. This disease will ...
Using the values from the second recorded measurement, enter the minute ventilation in the field below and then click Submit to record your answer in the lab report. You answered: 7500 ml/min 11. A useful way to express FEV1 is as a percentage of the forced vital capacity (FVC).
Using the FEV1 and FVC values from the data grid, calculate the FEV1 (%) by dividing the FEV1 volume by the FVC volume (in this case, the VC is equal to the FVC) and multiply by 100%. Enter the FEV1 (%) for an airway radius of 5. 00 mm in the field below and then click Submit to record your answer in the lab report. You answered: 74 12. A useful way to express FEV1 is as a percentage of the forced vital capacity (FVC).
Using the FEV1 and FVC values from the data grid, calculate the FEV1 (%) by dividing the FEV1 volume by the FVC volume (in this case, the VC is equal to the FVC) and multiply by 100%.
Enter the FEV1 (%) for an airway radius of 3. 00 mm in the field below and then click Submit to record your answer in the lab report.

You scored 100% by answering 5 out of 5 questions correctly. 1. To calculate a person’s vital capacity, you need to know the TV, ERV, and You correctly answered: c. IRV. 2. Measuring a person’s FVC means that you are measuring You correctly answered: d. the amount of air that can be expelled when the subject takes the deepest possible inspiration and then forcefully expires as completely and rapidly as possible. 3. Measuring a person’s FEV1 means that you are measuring You correctly answered: b. the amount of the VC that is expired during the first second of the FVC test. 4.
For a person suffering an asthma attack, inhaler medications are expected to You correctly answered: a. reduce the airway resistance. 5. Which of the following values does not include the ERV? You correctly answered: c. TV 010/24/12 page 5 Review Sheet Results 1. What would be an example of an everyday respiratory event the ERV simulates? Your answer: force expiration such as running, sneezing, and coughing 2. What additional skeletal muscles are utilized in an ERV activity? Your answer: abdominal muscle are utilized in an erv activity 3. What was the FEV1 (%) at the initial radius of 5. 0 mm? Your answer: 74 4. What happened to the FEV1 (%) as the radius of the airways decreased? How well did the results compare with your prediction? Your answer: fec1% decreases the same as the radius of the airway because the radius reduce the flow of air and my answer was correct 5. Explain why the results from the experiment suggest that there is an obstructive, rather than a restrictive, pulmonary problem.
