Instructions: Answer the following questions completely to receive full credit. This assignment is to be computer generated. NO EXCPETIONS!!! Provide a cover page (all pertinent information) for ALL assignments. Make sure to CHECK SPELLING for ALL assignments. NO LATE ASSIGNMENTS WILL BE ACCEPTED. This worksheet is worth 54 points. 1. Differentiate between the afferent and the efferent arterioles. (2 points)  Blood supply to the glomerulus o afferent arteriole  feed the glomerular capillary bed o efferent arteriole  drains the glomerular capillary bed 2. Provide a two-word description each for the renal corpuscle and renal tubules. (2 points)  renal corpuscle o glomerulus & glomerular together  renal tubules o reabsorption & secretion 3. What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the afferent arteriole? Explain!!! (2 points)  It decreases because there is less of an opening to get into. 4. What will happen to the glomerular capillary pressure and filtration rate if you increase the radius of the afferent arteriole? Explain!!! (2 points)  It increases because the opening is bigger allowing more fluid to pass. 5. What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? Explain!!! (2 points)  If decreased, then Glomerular Filtration Rate would increase because it allows more time for the fluid to be passed through. 6. The sympathetic nervous system decreases urine production. Logically, what do you think the sympathetic nerves do to the afferent arteriole? Explain!!! (2 points)  Sympathetic nerves innervate the afferent arteriole, causing smooth muscle contraction. This way there will be less urine production by closing off the afferent arteriole. 7. How is this effect (question #6) beneficial? Could this effect pose a potential problem if this condition continues? Explain!!! (3 points)  It beneficial because it allows...
