Surfactant has this affect on airflow because it reduces resistance to lung inflation 30. The following questions refer to Activity 4: Determining the Effect of Propylthiouracil on Metabolic Rate. Your answer: The results from the lab show that it is an obstructive airway because the airflow is constantly decreasing, if it was restrictive the volumes and capacities would have been affected more than what it was. During heavy exercise, further changes in respiration are required to meet the extreme metabolic demands of the body. Basically, alveolar ventilation becomes too great for the amount of carbon dioxide being produced. The more rapid the lines the more heavier the exercise. How well did the results compare with your prediction? To explain how the respiratory and circulatory systems work together to enable gas exchange among the lungs, blood, and body tissues 2.
Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise. The glucose transport rate will increase. Clicking Record Data after an experimental run will record your data for that run on the screen. Symbolically, an individual's perception of the world is constructed out of different influences, circumstances and events, which dictate how one responds to the world. You can ask any homework question and get expert homework help in as little as two hours. The Flow display on top of the vessel tells you the amount of air in liters being moved in and out of the lungs with each breath. Describe the effect that the inhaler medication had on the asthmatic patient.
Mama is the narrator of the story and she describes herself as being a big- boned woman with rough, man working hands. In the last part of this activity, you clicked the Reset button to draw the air out of the intrapleural space and return the lung to its normal resting condition. Molecules need a carrier protein to help them move across a membrane because Your answer : c. Reading the data from left to right, the first data field should be that of the Radius of the air flow tube 5. Surfactant increased the airflow 29. Carbon dioxide is the major component for regulating breathing rate. How well did the results compare with your prediction? The medication may also contain an antiinflammatory agent such as a corticosteroid that suppresses the inflammatory response.
The diaphragm moves to a flattened position. Describe the effect that the inhaler medication had on the asthmatic patient. What emergency procedure would be used to achieve this result if these were the lungs in a living person? Click the Start button notice that it immediately turns into a Stop button. What effect does the addition of surfactant have on the airflow? What lung values changed from those of the normal patient in the spirogram when the patient with emphysema was selected? Which volumes changed the most and when? When you are measuring air pressure, you are measuring the force that the air is exerting outwards, on whatever you are using to compress it since materials resist being compressed. I think that if the valve was opened and the two lungs were in a single large cavity rather than separate cavities both lungs would collapse. Look carefully—differences may be subtle. The X-axis displays elapsed time, with the length of the full monitor displaying 60 seconds.
Describe the effect that the inhaler medication had on the asthmatic patient. You publish photos in magazines and books and work with a printing house that likes to scan slides rather than negatives or prints. Thus a person with emphysema exhales slowly. A chest by insertion of tube to draw air out of pleural cavity and restore the pressure gradient 7. For example, in the atmosphere at sea level, the pressure is 760 mm Hg.
Note that when a measure button is selected, two things happen simultaneously: 1 a bracket appears on the spirogram to indicate where that measurement originates on the spirogram and 2 the value in milliliters appears in the data table. The results show that it is an obstructive airway because the airflow is constantly decreasing, if it was restrictive the volumes and capacities would have been affected more than what it was. Which of these volumes or capacities of the lungs changed the most in the patient with emphysema? Thus the volumes and peak flow rates are significantly reduced during an asthma attack. After 2 seconds, click Note that when a measure button is selected, two things happen simultaneously: 1 a bracket appears on the spirogram to indicate where that measurement originates on the spirogram and 2 the value in milliliters appears in the data table. What lung values changed from those of the normal patient in the spirogram when the patient experiencing an acute asthma attack was selected? Click Start and allow the trace to sweep across the full length of the oscilloscope monitor.
This is the circle that passes through all 3 vertices of the triangle. Heat is energy measured in Joules or other energy units eg calories. They dilate to increase flow The following questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. How well did the results compare with your prediction? Was there any difference from the effect of opening the valve of the left lung? Do you think a culture can be broken down into parts and still be understood? Inspiration actually becomes easier because the lung is now overly compliant. Now consider the accuracy of your predictions what changed versus what you expected to change. Before you perform the activities watch the Water-Filled Spirometer video to see the experiment performed with a human subject. Therefore, the total lung capacity the vital capacity volume plus the residual volume is approximately 6000 milliliters.
A tidal volume refers to theYou correctly answered: b. The breathing patterns of an individual are tightly regulated by the breathing centers of the brain so that the respiratory and circulatory systems can work together effectively. ¦ A C T I V I T Y 9 Comparative Spirometry In Activity 1, normal respiratory volumes and capacities are measured. Click the Start button and watch as the drum starts turning and a new spirogram develops. Remember, you may print your trace or your recorded data by clicking Tools at the top of the screen and selecting either Print Graph or Print Data. Do not delete your recorded data—you will need it for the next activity.
