Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it differs. Why did these values changeas they did? The changing of the airway radius in this lab simulation represents changing the size of the a. How well did the results compare with your prediction? What lung values will change from those of the normal patient in the spirogram when thepatient suffering an acute asthma attack is selected select all that apply? During an asthma attack You correctly answered: b. Design your own experiment for testing the effect of opening the valve of the right lung. What is the name of the emergency medical condition that opening the left valve simulates? Finally, notice the changes to the display windows below the oscilloscope screen. At the same time, carbon dioxide a waste product of metabolism from body tissues diffuses into the blood. Add Na+Cl- to the beaker on the left.
Predict Question 1: With emphysema, there is a significant loss of elastic recoil in the lung tissue and a noticeable, exhausting muscular effort is required for each expiration. What lung values changed from those of the normal patient in the spirogram when the patient with emphysema was selected? For liquids, you just put it in a volumetric measuring device such as a graduated cylinder, For the volume of solids that cannot simply be measured with L x W x H which will give you an answer in units of m … easurement cubed. Which respiratory process is impaired the most by emphysema? Why did these values change as they did? Recall that airflow is achieved by the generation of a pressure difference between atmospheric pressure on the outside of the thoracic cavity and intrathoracic pressure on the inside. A quilt is made up of patches of cloth intricately stitched together to make the final product. Now consider the accuracy of your predictions what changed versus what you expected to change.
What was the effect of reducing the radius of the air flow tube on respiratory volumes? ¦ A C T I V I T Y 3 Effect of Restricted Air Flow on Respiratory Volumes 1. Some ideas: ~Sell something in front of Walmart with permission ~borrow from someone ~ask your parents for 5. For a person suffering an asthma attack, inhaler medications are expected to. Respiratory System Mechanics 97 Acute Asthma Attack Breathing with Inhaler Medication Applied When an acute asthma attack occurs, many people seek relief from the symptoms by using an inhaler. A collapsed lung pneumothorax is a buildup of air in the space between the lung and the chest wall pleural space.
Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise. How well did the results compare with your prediction? Inspiration occurs as the external intercostal muscles and the diaphragm contract. 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. How well did the results compare with your prediction? 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. It decreased for both patients.
How well did the results compare with your prediction? Enter the minute ventilation in the field below and then click Submit to record your answer in the lab report. How well did the results compare with your prediction? How does this affect blood flow? Compliance, or the ability of the chest wall or lung to distend, is one. The chemical formula of glucose is: C6H12O6. What lung values changed from those of the normal patient in the spirogram when the patient experiencing an acute asthma attack was selected? Notice the buttons for Rapid Breathing, Rebreathing, Breath Holding, and Normal Breathing—clicking each of these buttons will induce the given pattern of breathing. The inhaler medication relieved the bronchospasms and induced bronchiole dilation. You may also print the trace on the oscilloscope monitor by clicking Tools and then Print Graph. Why did these values change as they did? Which of these volumes or capacities of the lungs changed the most in the patient with emphysema? Predict Question 2: What effect do you think adding Na+ Cl- will have on the glucose transport rate? What is the largest volume for the normal patient? Describe the effect that the inhaler medication had on the asthmatic patient.
The contraction of which of the following muscles will increase the thoracic cavityvolume during inspiration? It would decrease blood flow because the blood vessels constrict in anemics. Which respiratory process is impaired the most by emphysema? For a person suffering an asthma attack, inhaler medications are expected toYou correctly answered: a. The paper moves at a pre-set speed past the recording pen so that volumes per unit time can be easily calculated. How is having an acute asthma attack similar to having emphysema? Your answer: 74% Christopher Eberlein 4103825 4. The opening screen will look like Figure 7. This condition is known as pneumothorax, which we will investigate in this next activity. In the last part of the activity, you clicked the Reset button to draw the air out of the intrapleural space and return the lung to its normal resting condition.
As the amount of air in this space increases, the pressure against the lung causes the lung to collapse 6. Why does a pneumothorax frequently lad to atelectasis? The fev1 % decreased proportionally as the radius decreased which is characteristic of an obstructive pulmonary problem. What effect did opening the valve have on the left lung? Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The general name for the process that maintains the internal body temperature in humans is You correctly answered: a. . Why do you think some values did not return all the way to normal? What effect does the addition of surfactant have on the airflow? Describe the effect that the inhaler medication had on the asthmatic patient. How well did the results compare with your prediction? Taken from some larger, given, set, of course, of which both A and minus A are subsets.
I hope you understand what I'm tryinto say. How well did the results compare with your prediction? They dilate to increase flow The following questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. Why did these values change as they did? You may wish to click Tools and then Print Graph for a printout of your trace. Matthew 5-7 talks the importance of becoming self-successful before helping others, while Rumi discusses the need to love ourselves and become wiser. Reading the data from left to right, the first data field should be that of the Radius of the air flow tube 5.
Once the trace reaches the end of the screen, click the Stop button, then click Record Data. The diaphragm moves to a flattened position. Minute ventilation is the amount of air that flows into and then out of the lungs in a minute. How well did the results compare with your prediction? Undertake some research to find good literature to support your discussion. This loss of elastic recoil occurs as the disease destroys the walls of the alveoli.
After these selections are made and the existing spirogram screen clears, click the Start button and watch as the drum starts turning and a new spirogram develops as the paper rolls off the drum. Inspiration becomes easier because the lungs are more compliant. Repeat steps 5—7 of the Normal Breathing section in this activity. The question of the correct number of significant digits is undefin … ed and depends entirely on the number of significant digits available for the Atomic Mass of Magnesium. If there are any tracings on the oscilloscope monitor, click Clear Tracings. Do you think the drug propylthiouracil is used to. Now consider the accuracy of your predictions what changed versus what you expected to change.
