Total questions: 39
Worksheet time: 23mins
The urinary system consists of which organs
kidneys
ureter
urinary bladder
urethra
pancreas
The kidneys are posterior to the parietal peritoneum, AKA
retroperitoneal
Intraperitoneal
Subcutaneous
Endocrine
concave notch on medial side of kidney; where blood vessels, the ureters and nerves enter and leave the kidney
Hilum
Renal capsule
Renal cortex
Renal medulla
The right kidney sits lower than the left because of the space occupied by the liver just above it.
true
false
Outer region of the kidney, forms the site of urine production
renal cortex
renal medulla
inner region of the kidney; site of urine collection
renal medulla
renal cortex
Extensions from the renal cortex, that divide the interior region into cone-shaped sections
renal columns
renal medulla
minor calyx
major calyx
The interior of the kidney is divided into cone-shaped sections called
renal pyramids
Lobes
Chambers
Compartments
Match the following anatomy of the kidney terms
The point of the pyramid that faces the hilum
renal papilla
the renal papilla extends into a cup and this collects urine leaving the papilla
minor calyx
two or three minor calyces joined together
major calyx
The major calyces coverge to form this that recives the urine from the major calyces
renal pelvis
The tube-like structure that channels urine to the urinary bladder
ureter
Match the following terms
branches off the abdominal aorta and brings blood to the kidneys
renal artery
blood leaves the kidneys through this which empties into the inferior vena cava
renal vein
The filtration units of the kidney; primarily lie in the outer region
nephrons
cluster of capillaries inside the renal curpuscle
glomerulus
supplies blood to one nephron
afferent arterioles
blood leaves the glomerulus through this
efferent arteriole
network of capillaries around the renal tubules that lead to the larger veins
peritubular capillaries
location in the kidney where renal corpuscles reside
cortex
Ureter
Urethra
Glomerulus
portion of the nephron in charge of making urine is the:
renal corpuscle
renal tubule
bowman's capsule
afferent arteriole
one of the main components of nephrons, consisting of a glomerulus and Bowman's capsule, that filters blood plasma
renal corpuscles
Pulmonary artery
Renal tubule
Glomerular capsule
AKA glomerulus capsule- consists of two layers of epithelial cells surrounding the glomerulus in an open-ended covering
Bowman's capsule
Renal capsule
Nephron capsule
Series of tube-like structures within the nephron; where urine is formed
renal tubules
glomeruli
ureters
renal arteries
Select all the regions of the renal tubule
proximal convoluted tubule
loop of Henle
distal convoluted tubule
collecting duct
The amount of fluid filtered by all the glomeruli of both kidneys
Glomerular Filtration Rate
The number of capillaries in the renal cortex
The amount of oxygen delivered to the renal medulla
The volume of urine produced by the kidneys
U-shaped portion of the renal tubule
loop of henle
Glomerulus
Renal cortex
Juxtaglomerular apparatus
Also know as urination
micturition
Defecation
Elimination
Excretion
The presence of protein in the urine; an abnormal finding
proteinuria
A sign of good health
An indication of dehydration
Arising directly from Bowman's capsule; it's a winding, convoluted portion of the renal tubule. Thousands of microvilli line the inside of this structure
Proximal convoluted tubule
descending limb
loop of henle
collecting duct
After returning to the cortex, the ascending limb coils again forming this part of the renal tubule
distal convoluted tubule
collecting duct
proximal convoluted tubule
loop of henle
This receives drainage from the distal convoluted tubules of several different nephrons; eventually drains into a minor calyx
collecting duct
Ureter
Renal pelvis
How much urine do most adults produce a day?
1-2 liters
A few cups
Half a gallon
Several quarts
The wall of the bladder that consists of three layers of smooth muscle
detrusor muscle
Ureter
rugae
trigone
These folds appear when the bladder relaxes; they then smooth out when the bladder expands
rugae
detrusor muscle
trigone
urethra
Triangular shaped smooth area on the floor of the bladder formed by the openings for the two ureters and the urethra
trigone
ureters
rugae
detrusor muscle
ring of smooth muscle at the point where the urethra leaves the bladder that contracts involuntarily to retain urine in the bladder
internal urethral sphincter
external urinary sphincter
rugae
corpuscle
Sphincter of skeletal muscle where the urethra passes through the pelvic floor
external urinary sphincter
internal urethral sphincter
Diaphragm
Femur
small tube that conveys urine away from the bladder and out of the body
urethra
ureters
renal cortex
trigone
urination occurs when:
the bladder and internal urethral sphincter relax
the bladder and external urethral spincter contract
the bladder contracts and the external urethral sphincter relaxes
the bladder relaxes and the external urethral sphincter contracts
Glomerular filtration rate (GFR) should be constant, despite changes in blood pressure. What happens if the flow is too high?
the body will lose excessive water and nutrients.
The body will become dehydrated.
tubules may reabsorb toxins
The body will become more acidic.
Glomerular filtration rate (GFR) should be constant, despite changes in blood pressure. What happens if the flow is too low?
the body will lose excessive water and nutrients
tubules may reabsorb toxins.
The body will become malnourished
The body will become over-stimulated
What is the Urine made up of
95% water, 5% dissolved substances
85% minerals, 15% dissolved substances
95% proteins, 5% dissolved substances
95% electrolytes, 5% dissolved substances
What part of the bladder gets commonly infected?
trigon
detrusor muscle
rugae
urethra
The opening of the urethra leading to the outside of the body
external urinary meatus
External urethral orifice
External urethral passage
External urinary sphincter

200ml
400ml
100ml
50ml
In women, the _____ is shorter than it is in men, which contributes to the higher incidence of urinary tract infections in women.
urinary sphincter
urethra
loop of Henle
ureter
