Fred was diagnosed 6 months ago with liver cancer. His liver is no longer able to make the necessary amount of proteins needed by the body. What effect, if any, would this have on the net glomerular filtration rate? (Hint, decide which of the 3 forces contributing to the net filtration rate is affected. Then adjust numbers in the equation to determine if there is an increase, decrease, or no change to the net filtration rate). Group of answer choices A) Blood colloid osmotic pressure would be decreased, increasing the net glomerular filtration rate. B) Blood colloid osmotic pressure would be decreased, decreasing the net glomerular filtration rate. C) Capsular hydrostatic pressure would be decreased, increasing the net glomerular filtration rate. D) Capsular hydrostatic pressure would be decreased, decreasing the net glomerular filtration rate. E) There would be no effect on the net glomerular filtration rate.

. Briefly define filtration
Sketch each of the following segments of the nephron, and for each, write a short sentencedescribing how its epithelial structure suits its function.a. visceral layer of Bowman’s capsuleb. parietal layer of Bowman’s capsulec. proximal convoluted tubuled. thin segment/ loop of Henlee. collecting tubule
Water though Urinary System Trace the path of the water molecule as it moves from this starting point to this ending point. Starting point: The water molecule enters a kidney in the blood plasma traveling through the renal artery. Ending point: The water molecule is excreted from the body. You may write a description, create a diagram with labels, or both to trace a path. Include as many of the following components of the urinary system and terms as you can: afferent arteriolecollecting ductdistal convoluted tubuleglomerular capsuleglomerulusmajor calyxminor calyx nephron loopproximal convoluted tubulerenal pelvisureterurethra For each of the parts of the urinary system in your path, describe a unique anatomical characteristic (size, tissue composition, etc.) or function.

What tubules of the kidney would be most affected? Provide 2 examples from non-human species for removal of sodium. (short answer please)
