Solved in 4 steps
- 14. What happens to renal clearance ( the ability of the kidney to monitor blood ion levels) if Blood pressure falls? Explain in detail6. How is the rate of glomerular filtration controlled?4. Given the net glomerular filtration pressure of 55 mm Hg, a plasma protein osmotic force (TTGC) = 12 mm Hg, and a fluid pressure in Bowman's space (PBS) = 10 mm Hg, what would be glomerular capillary blood pressure (PGC)? Would filtration be favored under these conditions? How do you know?
- 4. What vital functions of the kidneys are performed by the nephrons?1. What determines which blood components remain in the blood and which components end up in the filtrate of the nephron? (i.e. Why do certain things pass through to Bowman's capsule while others can't?)7. In the absence of ADH (vasopressin) the concentration of tubular fluid solute is greatest at which of the following sites on the nephron? OA) B- O B) A D O C) HE OD) OE)
- 1. How does the filtration stage in excretory systems function?2. Add the following labels to the diagram below: collecting duct, loop of Henle, proximal tubule, distal tubule, glomerulus, Bowman's capsule The structure shown in the diagram above is called the6. Explain how the vertical concentration gradient in the medulla and the concentration of vasopressin influences the volume and osmolarity of urine produced.
