1) Functions of the Kidney are to __________toxins, _____________wastes, and excess _____ to urine,
and also to maintain ______________by regulating ___________and _______ makeup of the blood. There
are 3 processes for making urine, _____________, ____________, and_______________.
**2) The kidneys location is referred to as____________________. And the __________is the location
where the__________, renal blood vessels___________, and nerves ______and exit.
**3) In internal kidney anatomy the light colored granular __________region is referred to as the
________, while the tubular _________region is referred to as the __________which contains
______________which are the parallel bundles of urine-____________ and _____________ tubules that
drain urine through the papillae to the __________(calyx) which drain into the renal _________to the
___________to the urinary ___________and finally through the _____________to outside the body.
4) The structural and ____________units of kidney are the_________, and the blood is ____________in
the renal ___________which is made up of the _______________and the glomerulus_____________,
also referred to as the _____________ capsule.
5) The renal or _____________corpuscle has two layers, the external __________layer which is composed
of simple ___________epithelium which is the_________, and the ________layer which is modified simple
_____________epithelium, with branching epithelial _____________ with filtration ___________that
have openings between foot processes of podocytes allow filtrate to pass through the
______________endothelium, which is ____________endothelium which filters blood and allows soluterich and virtually _________-free filtrate to pass from __________into glomerular
capsule_____________.

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.
8) Every nephron has two capillary beds, the ___________and ______________capillaries. Each
glomerulus 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 _______from blood through the________.
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.
10) Filtrate contains no ________ but does contain all __________components
except_________. Water, ___________, and essential _________are reabsorbed as filtrate
and become _________ which contains water, ______________wastes, and unneeded substances.
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 3 to 4 minutes. Ureters enter bladder base through the
_____________wall and their ___________ends close as bladder pressure ___________which
prevents ____________of urine into ureters.
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.
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
____________.
14) Internal urethral sphincter is ___________muscle under _______________control and is
located at bladder-____________ junction. The external urethral sphincter is __________muscle
under __________ control, this sphincter ___________the urethra as it passes through
_______ diaphragm. The __________ ______muscle of pelvic floor is the second
_____________urethral sphincter.
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 external urethral orifice.
16) The kidneys develop from ________________as ureteric buds and in pouching of _______
forms the______________.
