URINARY Flashcards
against dorsal body wall
kidney
which kidney is lower?
R. Kidney
Organs of urinary system
Kidney
Ureters
Urinary Bladder
Urethra
what part of vertebrae can kidney be found
T12 L3
what is at the top of each kidney
adrenal gland
capsule that surround each kidney
Renal Capsule
provides protection to the kidney keeping it in correct location
Adipose Capsule
Regions of kidney
Renal cortex
medulla
pelvis
the outer region of the kidney
Renal cortex
this is the inner collecting tube in the kidney
Renal pelvis
the cortex contains the
Nephrons
the renal medulla / pyramid contains what
Ducts (FILTER)
cup shaped funnels urine towards renal pelvis
Calyces
the structural & functional units of the kidneys and forms urine
Nephrons
where filtration occurs
glomerulus
cupshape protecting the glomerulus
Bowmans Capsule
nephron in the cortex and filtration of blood pasma ;
Cortical nephron
nephrons found in the cortex and medulla
Juxta medulla nephrons
where are the proximal and glomerulus located
renal cortex
reabsorbs substances from collecting tubes
peritubular cappilaries
urine formation processes
Filtration
Reabsorption
Secretion
this is a nonselective passive process
Filtration
this occurs in the proximal tubule
reabsorption
yellow pigment from destruction of hemoglobin
Urochrome
stores urine
bladder
these are the three openings
trigone
the bladder wall is mucosa made of
transitional epithelium
which urethral sphincter is involuntary
internal
amount of water percentage in male and female
60 & 50%
this regulates sodium ion content of extracellular fluid
Aldosterone
what part of body where its cells are active monitors
Kidneys & hypothalamus
byproducts of cellular metabolism
Ions
molecules that react to prevent changes in hydrogen ion
Blood buffers
these react with strong acids to change them to weak acids
Bicarbonate ions
dissociates the presence of strong base to form weak base
Carbonic acids
