Textbook Question
Chapter 5, Problem 13TYK
Cells lining kidney tubules function in the reabsorption of water from urine. In response to chemical signals, they reversibly insert additional aquaporins into their plasma membranes. In which of these situations would your tubule cells have the most aquaporins: after a long run on a hot day, right after a large meal, or after drinking a large bottle of water? Explain.

Two solutions are separated by a semipermeable membrane that is permeable only to water. The two solutions are: Solution A = 150 mM KCl Solution B = 150 mM Angiotensin (a 7 amino acid polypeptide) Which of the following would best explain the net movement in this situation?
- water will move from the KCl side to Angiotensin side
- water will move from Angiotensin side to KCl side
- The Cl- ion will move to the angiotensin side until there is 75 mM Cl- on each side
- Since Angiotensin is not an ion, it can move through the membrane
- There is no net water movement as the concentrations are the same on both sides
Blood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?
Which process—diffusion, osmosis, or filtration—is utilized in the following situations? a. Injection of a drug that is hypertonic to the tissues stimulates pain. b. The urea concentration in the dialyzing fluid of an artificial kidney is decreased.

- A solution of water and dissolved ions is separated by a selectively permeable membrane that allows the passage of water but not small ions. The concentration of sodium is higher on one side of the membrane than onthe other side. However, there is no net movement of water across the membrane. How is this possible?arrow_forwardThe pathway that can move highest rates of sodium ions is: A. Sodium channels B. Sodium pumps-ATPases C. Sodium exchangers D. Sodium diffusion in solutionarrow_forwardWhen two chambers are separated by a membrane permeable to water but not solute, if water is free to move in either direction without limitation or pressure, then water will move until the concentration of solute on both sides of the chamber is equal move until there is no water on the dilute side move until there is no water on the concentrated side move until the concentration of water on both sides of the chamber is equalarrow_forward

What would happen if the dialysis membrane were permeable to water but not solutes?arrow_forwardA student designed an experiment to test whether different concentration gradients affect the rate of diffusion through dialysis tubing. Four different solutions (0% NaCl, 1% NaCl, 5% NaCl, and 10% NaCl) were tested under identical conditions. Twenty mL of each solution was placed into separate dialysis tubing that is permeable to Na+, Cl-, and water. Each bag was placed in a separate beaker and covered with distilled water. The concentration of NaCl in the water outside of each bag was measured at 40-second intervals. The graph below shows the results from the 5% bag: Concentration of NaCl Outside of Dialysis Bags Concentration of NaCl (mg/L) 400 320 240 160 80 0 40 80 Time(seconds) 120 5% Solution 160 a. Describe the process of diffusion through the dialysis tubing. b. If you were to design a different experiment testing rates of diffusion, identify experimental procedures. c. Analyze that data in the graph and describe the results. Provide reasoning to justify your answer. d.…arrow_forward
- Investigate the processes of diffusion and osmosis and how they relate to kidney dialysis. You may also throw in some other daily home applications of diffusion and osmosis if you want to!arrow_forwardWhen the kidneys filter plasma, the filtered glucose is reabsorbed from the renal tubules and is not passed in the urine. However, glucose can appear in the urine when the blood sugar is exceptionally high. Given that glucose is reabsorbed by carrier-mediated transport, what functional aspect of carrier-mediated transport does the appearance of glucose in urine demonstrate? Explain.arrow_forwardSevere vomiting and diarrhea cause a loss of water and solutes from extracellular fluids. If the person was given only water, what effect would this have on the solute concentration of the extracellular fluids? Would osmosis results in water entering or leaving cells?arrow_forward
- For the following scenario you must draw the situation depicted, indicate which solution is hypertonic, hypotonic or isotonic (as applicable), and then show with arrows which way water will move. Then you must write your response in complete sentences, thoroughly explaining and justifying your arrows. a. Ouch! Sore throat! It is so swollen that it is sore and it is difficult to swallow. And you have an oral presentation today. Better gargle with salt water to reduce the swelling! Explain why this age old technique really works, by using the concept of osmosis.arrow_forwardThe functional unit of the mammalian kidney is similar to a piece of dialysis tubing. Quantities of blood plasma that contain dilute amounts of the waste product urea are filtered into the nephron. The concentration of urea in the developing urine is increased by moving water from inside the nephron to the outside. Urea is a larger molecule than water, and unlike water, cannot pass through the membrane of the nephron. Imagine you have been given a piece of dialysis tubing that simulates the nephron membrane, a dilute solution of urea in water, and a beaker of salt water. Applying the concepts and methods used in this investigation, describe how you could concentrate the dilute solution of urea. You can use a drawing to help explain your ideas.arrow_forwardSo, in peritonitis, there is an inflammation of the peritoneum and a build up of fluid/exudate in the abdomen. With this third spacing, fluid is lost to the individual. Isotonic solution makes sense to replace the fluids, colloids, electrolytes, etc... that are lost because of this. However, in theory, couldn't a hypertonic solution pull this fluid that is into the third space back into the intravascular space?arrow_forward
