|
performs the vital function of removing the organic waste products generated by cells throughout the body
|
urinary system
|
|
|
located on either side of the vertebral column between the last thoracic and third lumbar veretbrae
|
kidneys
|
|
|
an indentation site of exit for the ureter, as well as the site at which the renal artery and renal nerve enter and the renal vein exits
|
hilum
|
|
|
microscopic tubular structures where urine begins, and is also the main functional unit of the kidney
|
nephrons
|
|
|
a capillary network in Bowman's Capsule where blood is filtered
|
glomerulus
|
|
|
blood pressure forces fluid and dissolved solutes out of the glomerular capillaries and into the surrounding capsular space
|
filtration
|
|
|
filtration produces a protein-free solution know as
|
filtrate
|
|
|
forms the outer wall of the renal corpuscle and encapsulates the glomerular capillaries
|
bowmans capsule
|
|
|
composed of a descending limb that travels toward the renal pelvis and an asceding limb that returns to the cortex
|
loop of Henle
|
|
|
the removal of water and solute molecules from the filtrate and their reentry into the circulation at the peritubular capillaries
|
reabsorption
|
|
|
the transport of solutes out of the peritubular capillaries, across the tubular epithelium, and into the filtrate.
|
secretion
|
|
|
where reabsorption of Sodium 65% and Chloride occurs via active transport
|
Proximal Tubule and Bowmans Capsule
|
|
|
where water 20% is reabsorbed via osmosis
|
Decending limb of loop of henle
|
|
|
where electolytes are reabsorbed via simple diffusion
|
ascending limb of loop of henle
|
|
|
the process of filtrate production at the glomerulus is called
|
glomerular filtration rate
GFR |
|
|
Glomerular filtration rates
|
125 mL per minute
180 Liters per day |
|
|
the most abundant organic waste. you generate 21 grams per day
|
Urea
|
|
|
generated in skeletal muscle tissue through the breakdown of creatine phosphate, which is a high-energy compound that plays an important role in muschle contraction
|
Creatinine
|
|
|
produced during the breakdown and recycling of RNA. you generate about 480 mg each day
|
Uric Acid
|
|
|
blood tests done to show levels of efficiency of nephrons/GFR=Discovery of Renal failure
|
Blood Urine Nitrogen (BUN) and Creatinine(waste product of metabloism that is not resorbed)
|
|
|
pain associated with hollow organs=aching/cramping pain
|
visceral pain
|
|
|
pain spread out due to activation of many pain receptors and nerve signals
|
referred pain
|
|
|
flank pain (visceral) and referred pain to shoulder and neck of same side
|
Pyelonephritis (infection of nephrons that also cause fever)
|
