(50 cards)
what is the major excretory system of the body
urinary system
what does the urinary system eliminate
waste and excessive products
what is formed in protein metabolism
nitrogenous waste
urine is formed from ammonia into
urea
what are the 4 parts of the urinary system
kidneys
ureters
bladder
urethra
what is the unit that filters blood, removing waste and forming urine
kidneys
what is urine (4)
- excess H2O
- excess ions
- metabolic wastes
- toxic substances
what is the shape of the kidney
bean shaped
where is the kidney located
T12 to L3
where is the arterial supply from for the kidney
renal arteries off aorta
where is the venous supply from for the kidneys
renal veins
where do the renal veins drain into
IVC
what kidney is slightly lower than the other and why
right is lower because of locations of liver
the kidneys are what kind of paired organs
retroperitoneal
each kidneys lies where
lateral to the vertebral column
on posterior abdominal wall largely under cover of the costal margin
in the supine position the kidneys extend from
T12 superiorly to L3
with contraction of the diaphragm during respiration, both kidneys move
downward
what are the 6 functions of the urinary system
- excretion
- regulation of BV and BP
- regulation of blood solute concentrations
- regulation of extracellular fluid pH
- regulation of RBC synthesis
- regulation of vitamin D synthesis
does the urinary system maintain homeostasis
yes
what filters waste products and bodys plasma vilume
excretion
what controls ECF of body
regulation of BV and BP
the regulation of BV and BP are dependent on
hydration
during regulation of BV and BP it produces large volume of dilute urine or small volume of what
concentrated urine
control of BV, thereby control BP via
urine production
