BIO 202 ASU Practical 3 (Final
Practical)
Urinary system organs - answer kidneys, urinary tract
Urinary tract organs - answer ureters, urinary bladder, urethra
kidneys filter the blood to remove _______ __________ - answer metabolic wastes
kidneys regulate - answer body’s fluid, electrolyte and acid-base balance
what are some extra functions of the kidneys - answer help the liver detoxify
make glucose during times of starvation
produce the hormone erythropoietin
are the kidneys paired or unpaired and are the peritoneal or retroperitoneal - answer
paired, retroperitoneal
what three layers encase the kidney - answer renal fascia, adipose capsule, renal
capsule
renal fascia function - answer anchors the kidneys to the posterior abdominal wall and
peritoneum ( made of dense irregular collagenous connective tissue)
adipose capsule function - answerwedges the kidneys in place
renal capsule function - answerencases each kidney like plastic wrap (made of dense
irregular collagenous connective tissue)
renal hilum - answermedial indentation where blood vessels and the ureter enter and
exit
what are the three regions of the kidney - answerrenal cortex, renal medulla, renal
pelvis
renal cortex - answermost superficial region, dark brown because of many blood
vessels that serve the nephrons
renal medulla - answermiddle region, contains renal pyramids and renal columns
renal pyramids - answerstriated, contain looping tubules of nephrons as well as
structures that drain fluid from the nephrons
, renal columns - answerinward extensions of the renal cortex
renal papilla - answertip of the renal pyramid
renal pelvis - answerserves as a basin for collecting urine
the renal arteries branch into the - answersegmental arteries, interlobar arteries, arcuate
arteries, and cortical radiate arteries
where are the segmental arteries - answerthe renal pelvis
where are the interlobar arteries - answerbetween the medullary pyramids
where are the arcuate arteries - answercurve around the top of the pyramids
where are the cortical radiate arteries - answerin the renal cortex
what do the cortical radiate arteries branch into - answerthe afferent arterioles
what do the afferent arterioles supply - answerthe ball of capillaries known as the
glomerulus
glomerulus function - answerwhere blood is filtered NOT the primary site for gas and
nutrient exchange
the capillaries of the glomerulus drain into a second arteriole called the - answerefferent
arteriole
the efferent arteriole branches to form the - answerperitubular capillaries
peritubular capillaries function - answerprovide tubules of the nephron with gas and
nutrient exchange
what is the flow of blood through the veins in the kidney - answerperitubular capillaries >
cortical radiate vein > arcuate vein > interlobar vein > renal vein
microscopically each kidney is composed of a million tiny units called - answernephrons
what are the two parts of the nephron - answerrenal corpuscle and renal tubule
what are the two parts of the renal corpuscle - answerglomerulus and glomerular
capsule
what are the two layers of the glomerular capsule - answerparietal layer (simple
squamous epithelium) and visceral layer (podocytes) (capsular space is between)
