REVIEW SHEET EXERCISE 4 Endocrine System Physiology NAME: LAB TIME/DATE: Metabolism The following questions refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate? The normal rat had the fastest baseline metabolic rate. 2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The normal rat’s baseline metabolic rate was faster than that of the thyroidectomized rat’s

emphysema was selected? Why did these values change as they did? 6. Which of these two parameters changed more for the patient with emphysema‚ the FVC or the FEV1? 7. How is having an acute asthma attack similar to having emphysema? How is it different? 8. Describe the effect that the inhaler medication had on the asthmatic patient. 9. How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication? 10. With moderate aerobic exercise‚ which

attempts to diffuse glucose and albumin through the 200 MWCO membrane. 7. Put the following in order from smallest to largest molecular weight: glucose‚ sodium chloride‚ albumin‚ and urea. ACTIVITY 2: Simulated Facilitated Diffusion Answers 8. True or False: The facilitated diffusion of glucose requires energy from ATP. 9. Which of the following might cause the facilitated diffusion of glucose from one solution to another to occur faster? a. Add Na+Cl- to the beaker on the left. b

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

Respiratory Mechanics 1 Note there is an error in your lab book! The starting radius for the flow tube diameter should be 5mm in each experiment and NOT 6mm.Use your computer link to ADAm for this part of this week’s lab. You are also responsible for the PowerPhys lab report. Measuring Normal Respiratory Volumes 1) Calculate the minute respiratory volume using the tidal volume and breaths per minute (pump rate). 2) Define the following terms: a. Respiration- The act of breathing

Inverse 7. Was the effect of viscosity greater or less than the effect of radius on fluid flow? Why? Less‚ the radius of blood vessels effect flow more because the large vessels allow more blood to flow through regardless of its viscosity. 8. What effect would anemia have on blood flow? Why? It would decrease blood flow because the blood vessels constrict in anemics. The following questions refer to Activity 3: Studying the Effect of Flow Tube Length on Fluid Flow. 9. At what flow

The Respiratory System STRUCTURAL PLAN Basic plan of respiratory system would be similar to an inverted tree if it were hollow; leaves of the tree would be comparable to alveoli‚ with the microscopic sacs enclosed by networks of capillaries (Figure 14-1) Passive transport process of diffusion is responsible for the exchange of gases that occur during respiration. RESPIRATORY TRACTS Upper respiratory tract—nose‚ pharynx‚ and larynx Lower respiratory tract—trachea‚ bronchial tree‚ and lungs

The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the
