Rename this document to include your first and last name prior to submitting, e. Respiratory System Mechanics: Computer Simulation. What emergency medical condition does opening the valve simulate? Activity 1 What do tubes 2, 6, and 7 reveal about pH and amylase activity? Boiling inactivates, or denatures, enzymes. It is a more sensitive parameter and not as reproducible as the others. Tubes 1 and 2 contained the same substances. Surface tension was sequentially decreased.
What effect did opening the valve have on the left lung? The motor neuron and muscle fiber intersect at what is called You correctly answered: d. Despite themedication allowing for greater air movement the patient is asthemic because the lateral value will never reach normal. The respiratory condition of pneumothorax refers toYou correctly answered: c. There was an airway resistence due to the increase in mucous secretion. Why do you think some values did not return all the way to normal? How is this change in whole-muscle force achieved in vivo? Surface tension acts to increase the size of the alveoli within the lungs. We found several results for Physioex 8 0 Exercise 7 Answer Key.
Opening the valve in the side of the glass bell jarYou correctly answered: d. As the stimulus increased the muscle tension also increased but not in proportion. Calicum levels are low since muscle contaction is not at its peak. Having an acute asthma attack is similar to having emphysema in that the airways collapse and pinch closed before a forced expiration is completed. Rebreathing When Rebreathing is clicked, a small bag will appear over the end of the air tube to allow the air within the lungs to be repeatedly inspired and expired.
What lung values will change back to those of the normal patient in the spirogram after the asthma patient uses an inhaler select all that apply? These changes are due to the loss of elastic recoil in the lung tissue and a noticeable, exhausting muscular effort is required for expiration. Condition where inadequate… 748 Words 3 Pages Exercise 7. This phase is the period of time prior to muscle contractions, however chemical changes in the cells occur in preparation for muscle contractions. In Activity 2, how long was the latent period? The threshold voltage was 0. Give one possible explanation for this. What affect does boiling have on enzyme activity? New to the site was just hoping if someone had the answers to phsyio-ex 8.
Which respiratory process is impaired the most by emphysema? Activity 2 Which tubes showed that starch or cellulose was present? The constriction of the efferent radius will limit blood drainage out of the glomeruli and that requires increasing the glomerular filtration rate. Skeletal muscles are composed of hundreds to thousands of individual cells called Your answer : b. How is having an acute asthma attack similar to having emphysema? The inhaler medication relieved the bronchospasms and induced bronchiole dilation. Experiment Data:Radius Breath Rate Surfactant Pressure Left Pressure Right Flow Left Flow Right Total Flow5 15 0 -4 -4 49. Your answer: Both an acute asthma attack and emphysema cause a contriction and pinch close before expiration is completed. From Activity 3, describe the effect of increasing the voltage. My result went well… 5650 Words 23 Pages Management, 10e Robbins Chapter 7 Foundations of Planning 1 Planning is concerned with how objectives are to be accomplished, not what is to be accomplished.
Your answer:It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. The active force will first increase and then plateau at some maximal value as the stimulus voltage increases. The motor neuron and muscle fiber intersect at what is called Your answer : b. You may delete these instructions before submission. Skeletal Muscle Physiology Activity 1 1.
Air flowsfrom the lungs causing the collapse of the lung. Why did these values change as they did? What is the largest volume for the normal patient? Student instructions: Follow the step-by-step instructions for this exercise found in your lab manual and record your answers in the spaces below. My first reaction was that he went a little bit too far with that statement, I think unattractive women and attractive women could have or not have an easier access to the mainstream of society as… 2091 Words 9 Pages right of the Hyperventilation button. What emergency medical condition does opening the left valve simulate? How well did the results compare with your prediction? Hint: Look at the results for tube 4. Latent-stage from rest to muscle tension begins b. Why do you think some values did not return all the way to normal? Which of the following processes does not occur during inspiration? The lung will remain collapsed.
Explain why their optical density measurements were different. What lung values changed from those of the normal patient in the spirogram when the patient experiencing an acute asthma attack was selected? Lung is overly compliant and expands easily. What would you need to do to make the left lung function properly again? For these purposes the payment frequency does not matter. Download links for Physioex Exercise Answer Key For Physioex. The diaphragm moves to a flattened position. What would be the proper accounting treatment for the following treatment…. When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch.
