Activities 4-6 Renal Response to Normal Acid-Base Balance, Renal Response to Respiratory Alkalosis, and Renal Response to Respiratory Acidosis were consolidated into a single activity, Activity 3: Renal Responses to Respiratory Acidosis and Respiratory Alkalosis. Describe one way in which osmosis is similar to simple diffusion and one way in which it is different? What are the components of the renal corpuscle? Calculate the oxygen consumption per hour for this rat using the following equation. After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. The two variables that affect the rate of diffusion are: A.
Serological Testing Major changes to PhysioEx content since version 8. The afferent arteriole dilation improved the low glomerular capillary pressure and filtration rate marginally. Predict Question 3: What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? How did increasing the afferent arteriole radius affect glomerular filtration rate? Describe two variables that affect the rate of diffusion. What is the major ingredient that needs to be removed from the blood?. The sodium-potassium pump is classified as a n You correctly answered: a. For this reason, an increase in urine volume would stabilize blood volume. Explain why the rate increased.
The thyroidectomized Tx rat is You correctly answered: a. There was an exponential response, which was depicted on the graph. Your answer: Glomerulus and Glomerular Bowman's capsule 3. The growing body of knowledge in the health of a human being substantiates… Exercise 1: Cell Transport Mechanisms and Permeability: Activity 5: Simulating Active Transport Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. How well did the results compare with your prediction? Your answer: By decreasing the radius of the afferent arteriole, the glomerular capillary pressure and the glomerular filtration rate decreased. Use an analogy to support your statement. Drag the next slide patient B to the fluorescent microscope.
Activity 4: Stimulating Filteration 1. None of the rats developed a goiter with this injection. In the extracellular solution just outside the cell body 2. The increase of flow tube radius increased the flow rate, as predicted. Your answer: You can co nstrict or dilate them. My results went well compared to my prediction… PhysioEx 9. How did decreasing the efferent radius affect glomerular filtration rate? This is what I predicted to happen.
If all other variables are kept constant, when blood pressure decreases, glomerular filtration Your answer: b. The extracellular Na+ did not alter the membrane potential in the resting neuron because the Na+ channels were mostly closed. The 10mM glucose molecules were able to diffuse from the right beaker to the left beaker until equilibrium was reached, meaning that both the left and the right beaker contained the same concentration of glucose. Which of the following is true of enzymes? After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. What is the approximate concentration of Na+ outside a cell extracellular concentration? No the rate of diffusion may be either very rapid or gradual.
Therefore the addition of the carriers would have no effect on the transport of sodium and potassium ions. An analogy that I would use to support this process is a coffee maker filter. How well did the results compare with your predictions. Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. However, it does not increase the concentration of solutes that passes through the membrane. In the serology test just performed, the fluorescence is found on the You correctly answered: c.
A negative membrane potential was recorded when the tip of the microelectrode was: a. If all other variables are kept constant, how does blood pressure affect the rate of glomerular filtration select all that apply? Activities 4 and 5 Investigating Treppe and Investigating Wave Summation were consolidated into a single activity, Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction. Which of the following caused a change in membrane potential from -70 to -40 in the cell body? Sodium chloride, urea, glucose, and albumin Simulated Facilitated Diffusion 1. Increase in blood vessel radius is more likely to occur. Activities 7-9 Respiratory Response to Normal Metabolism, Respiratory Response to Increased Metabolism, and Respiratory Response to Decreased Metabolism were consolidated into a single activity, Activity 4: Respiratory Responses to Metabolic Acidosis and Metabolic Alkalosis. The results from the experiment supported these predictions because as the number of glucose carriers increased the rate of glucose transportation via facilitated diffusion also increased. Calculate the oxygen consumption per hour for this rat using the following equation.
How does each mechanism specifically alter the glomerular filtration rate? You answered: 0 elementary bodies 16. The results I obtained from the experiment supported these predictions because as we increased the pressure the filtration rate increased as well but it had no effect on the concentration of the solute. What is the approximate concentration of Na+ inside a cell intracellular concentration? Drag the first slide patient A to the fluorescent microscope. Therefore, the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. The normal rat is You correctly answered: c. Activities 6 Obtaining a Glucose Standard Curve and 7 Measuring Fasting Plasma Glucose were consolidated into a single activity, Activity 2: Plasma Glucose, Insulin, and Diabetes Mellitus. The thyroidectomized Tx rat is You correctly answered: a.
An introduction that defines a problem, stresses its importance, and offers a brief description of the proposed solution. Count the number of elementary bodies you see through the microscope recall that elementary bodies stain green , enter the number of elementary bodies in the field below, and then click Submit Data to display your results in the grid. How well did the results compare with your prediction? In the absence of other renal processes including tubular reabsorption and secretion , more glomerular filtration leads to a larger urine volume. Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the per kilogram of body weight with the following equation note that you need to convert the weight data from grams to kilograms to use this equation. You answered: 0 elementary bodies Post-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly.
