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 …show more content…
What will happen to the urine volume and concentration as the solute gradient (concentration) in the interstitial space is increased? Explain!!! (3 points) It increases because ADH causes water to move out of urine and the more solute there is the more concentrated the urine. 16. Speculate on ways that desert rats are able to concentrate their urine significantly more than humans? (Think: Hormones) (2 points) They probably produce more ADH to get all the water possible from the urine as there is not a lot of water in the desert. 17. What would be a reasonable mechanism for diuretics? (2 points) They act by diminishing sodium reabsorption at different sites in the nephron, thereby increasing urinary sodium and water loss. 18. What will happen to the glucose concentration in the urinary bladder as glucose carriers are added to the proximal tubule? Explain!!! (2 points) Glucose concentration in the urine decreased because the carriers were able to get the glucose across. 19. Predict what will happen to the urine volume (compared to normal) when aldosterone is added to the distal tubule. Explain!!! (2 points)
