7) There are two nephron types, majority being the ______nephrons located mostly in ______which produce ______urine, while the ______nephrons have their glomerulus located near ______-______junction and their Loops of______dip deeply into ______with extensive thin segments and produce ______urine. 5D5

8) Every nephron has two capillary beds, the ______and ______capillaries. Each gomerulus is fed by an______arteriole and then drained by an ______arteriole which are ______than the afferent. The afferent are ______to accommodate the ______blood pressure so fluids and solutes are______fromblood through the______.5D5

9) Peritubular capillary beds are under______-pressure and are______capillaries adapted for ______they arise from ______arterioles, cling to adjacent renal ______and empty into renal ______system. 5D5

10) Filtrate contains no______but does contain all ______components except______. Water, ______, and essential ______arereasorbed as filtrate and become ______which contains water, ______wastes, and unneeded substances. 5D 5

11) Ureters have a______wall of ______epithelial mucosa, ______muscle muscularis and fibrous connective tissue______. The ureters actively propel urine to bladder via ______at intervals of 3to 4 minutes. Ureters enter bladder base through the______wall and their ______ends close as bladder pressure ______which prevents______of urine into ureters. 5D6

12) At the base of the urinary bladder is where the ______is located, which is a______area outlined by the openings for______and______, this is clinically important because ______tend to persist here when the bladder does not ______-completely. 5D6

13) Bladder wall is composed of ______epithelial mucosa, which is shed into the ______when there is urinary tract______. The ______muscle is thick ______muscle layer which ______when you urinate forcefully and fibrous ______. 5D6

The external urethral sphincter is______muscleunder______control, this sphincter ______the urethra as it passes through ______diaphragm. The ______muscle of pelvic floor is the second ______urethralsphincter. 5D7

15) In the male urethra the prostatic urethra runs within ______gland, the ______urethra runs through urogenital diaphragm, and the ______penile urethra passes through the______and opens via externalurethral orifice. 5D7

16) The kidneys develop from ______as ureteric buds and an in pouching of______forms the______.5D8
