Step by step
Solved in 2 steps
- Describe the four functional regions of the mammalian kidney.is the human kidney a model for all mammalian kidneys?The kidney of a cactus wren is less efficient at concentrating urine than are the kidneys of a kangaroo rat. However, the cactus wren produces less urine. Explain this apparent contradiction.
- Describe what happens during the following stages in urine forma-tion in the mammalian nephron: filtration, tubular reabsorption, tubular secretion.Define nitrogenous wastes, and list the main types produced in animals.What are some advantages and disadvantages of excreting differenttypes of nitrogenous wastes?The renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations. For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion Explain how you determined this.
- 3. 10iammals, With some exceptions, are the only vertebrates with medullary nephron. All other vertebrates only have a cortical nephron. What does this mean for the osmolarity of the renal filtrate for these vertebrates and what problems might this present? How do think they solve this problem? Search entries or author Unread Edit View Insert Format Tools TablePlease define/describe the following 3 renal functions in mammals: filtration, reabsorption and secretion. Describe at least one location in the nephron where each of these functions takes place. How does each of these functions contribute to homeostasis of the organism?Draw a schematic diagram showing the flow of water and salts in the proximal tubule of the kidney. In this diagram, put the lumen on the left side of the diagram and the extracellular fluids on the right side of the diagram. Indicate where the lumen is, where the extracellular fluid is, where the apical portion of the cell is, and show the location of the proteins that are responsible for the movement of water and salts and glucose reabsorption in this area of the kidney
- Why is there a need to modify the ultrafiltrate along thetubules of the mammalian kidney? please provide scientific explanations and do not just copy from google or i will downvoteThe loop of Henle in the mammalian renal tubule…The bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.)
