Glomerular filtration rate and pressure will rise above baseline values. B Membrane of most cells contains K+ leak channels…. The concentration of glucose becomes zero because when 400 glucose carriers were added, enough were added to facilitate the re-up of glucose. How could increased urine volume be viewed as being beneficial to the body? If all other variables are kept constant, how does blood pressure affect the rate of glomerular filtration select all that apply? If all other variables are kept constant, how does the afferent arteriole radius affect the rate of glomerular filtration select all that apply? This observation would be due to the increased temperature of the water, which helps aid in diffusion. This easy-to-use software consists of 13 modules containing 77 physiology lab simulations that may be used to supplement or substitute for wet labs. The carriers are able to carry glucose across the walls of the glomerulus for the reabsorption. True or False: Drinking a lot of caffeine coffee or cola leads to an increased urine volume.

Your answer: There was a greater increase of glomerular pressure when afferent radius is increased rather than the decrease of the efferent radius. My results went well compared to my prediction… physioex 9. Discuss the relative permeability of the membrane to Na+ and K+ in a resting neuron. The kidneys regulate excreting water and sodium into urine, to regulate blood volume Klabunde, 1998-2010 : 1. Increase in blood pressure can be increase in blood volume. What changes are seen in nephron function when the valve is closed? In the absence of other renal processes including tubular reabsorption and secretion , more glomerular filtration leads to a larger urine volume.

How did the urine volume change? In this simulation, when the radius of the afferent arteriole was 0. Loop of Henle U-shaped hairpin loop 3. What is the glomerular filtration rate? What are the components of the renal corpuscle? Increase in blood pressure can be increase in blood volume. If all other variables are kept constant, how does the efferent arteriole radius affect the rate of glomerular filtration select all that apply? An afferent arteriole supplies the blood to the glomerulus. There are over 100 different types of cancer; however all cancers begin because abnormal cells grow out of control. The Kidneys are located in the abdominal cavity, with the right kidney just below the liver, and the left kidney below the spleen. This might result from a decrease in the radius of the efferent arteriole.

Pressure will increase and filtration rate will decrease. Rename this document to include your first and last name prior to submitting, e. This left nothing in the unabsorbed water and became urine. This means more water can be reabsorbed making urine volume less and keep water balance. When the radius of the afferent arteriole was 0.

Renal mechanisms have effects on water excretion. A decreased efferent arteriole radius will decrease the rate of glomerular filtration. Match each of the definitions in Column A with the appropriate term in Column B. True or False: The renal system the kidneys is very important in regulating plasma osmolarity, plasma volume, and the body's electrolyte balance. If blood pressure goes down, the rate of glomerular filtration goes up. Compare this data with your baseline data.

True or False: Drinking a lot of caffeine coffee or cola leads to an increased urine volume. If blood pressure went down for example, as the result of blood loss what changes would the kidney need to make to maintain its normal filtration rate? Exercise 9: Renal System Physiology: Activity 3: Renal Response to Altered Blood Pressure Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. In this simulation, you varied the number of glucose carriers. Your answer: There are less sodium leak channels than potassium leak channels, and more of the potassium channels are open. As pressure increased, what happened to the pressure in the glomerulus? You can ask any homework question and get expert homework help in as little as two hours. Which of the following statements about metabolism is false? If all other variables are kept constant, how does the afferent arteriole radius affect the rate of glomerular filtration select all that apply? What types of transport are utilized during glucose reabsorption and where do they occur? Thyrotropin-releasing The normal rat is You correctly answered: c. Concentration of urine was increased.

If you close the one way valve, pressure will increase in the Bowman's capsule and filtration rate will decrease. The afferent arteriole dilation improved the low glomerular capillary pressure and filtration rate marginally. This is what I predicted to happen. What are two primary functions of the kidney? How did increasing the systemic blood pressure alter the results when the valve was closed? What are the components of the renal corpuscle? What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the afferent arteriole? I would really appreciate any help that can be given. All of the above are correct. Describe two Variables that affect the rate of diffusion. Describe the effect of decreasing the afferent arteriole radius on glomerular capillary pressure and filtration rate.

Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? If blood pressure went down — for example, as the result of blood loss — what changes would the kidney need to make to maintain its normal filtration rate? The membrane is more permeable to potassium because of the higher number of potassium leak channels. An increase in urine volume can stabilize blood volume. Activity 5: Reabsorption of Glucose 1. What happened to the urine volume as the concentration gradient increased? If blood pressure goes down, the rate of glomerular filtration goes down. Excretion-filters The increase of blood pressure can increase blood volume and the increase of urine volume will help to stabilize blood volume. For this reason, an increase in urine volume would stabilize blood volume. In this simulation, you varied the number of glucose carriers.

The normal rat is You correctly answered: c. When you increase the blood pressure, the glomerular capillary pressure and the glomerular filtration rate will also increase. True or False: Renal processing of glucose that is filtered in the glomeruli is primarily by secretion back into the blood stream. With the lack of glucose carriers, a less amount of glucose is transported. Acute Renal Failure is dangerous because the kidney stop filtering toxin, waste and excess fluids from the the body. What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? What would you expect to find in the urine of a diabetic? Which of the following statements about metabolism is false? I will investigate the Importance… 1256 Words 6 Pages Chronic renal failure is a worldwide public health problem.
