urinary review Flashcards
where in the body is urea produced
liver
what molecules form urea
co2 and NH2
what is the functions of kidney
filteration, ph adjustment and water balance
the proximal con tubule have what cells for increased surface area
mircovilli for tubular reabsorption
the cells in distal con tubers have what
mitochondria but lack mircovilli
what is glomerular/pressure filtration
blood pressure forces water and molecule from the glo into the glo capsule
what is tubular secretion
substances are removed from blood and added to the tubular fluids in distal tubule
where is the concentration of salt hugh
in the inner medulla
what process is in the proximal con tubules
tubular reabsorption
what process occurs in the distal con tubule
tubular secretion
what is the ADh made and stored
hypothalamus and stored in the posterior pituitar gland
ANH inhibits what
renin and aldosterone
what causes diuresis
caused by alcohol and inhibits secretion of ADH
what converts angiotensinogen to angiotensin 1
renin
what is a solution produced when blood is filtered though walls of glo
Pressure filtration
what has the greatest glucose concentration in nephron
glomerular capsule
what part of the kidney is the ureter connected too
renal pelvis
filtrate enter glo capsule by
pressure filtration
urea is a waste product if metabolism of
proteins
Damage to the glomerulus could lead to the presence of
red blood cells in the filtrate
An increase of ADH in the blood affects the water content of the blood plasma by
increasing he permeability of the collecting duct.
Increasing the levels of aldosterone in the blood would result in
increased blood levelsn
Which substance is found in the glomerulus, glo capsule and afferent arteriole but is not normally found in the collecting duct?
glucose
nutrients and salt ions are selectively reabsorbed into the
peritublar capillaries
what does the afferent arteriole do
senses blood pressure for filtration.
what does the proximal com tubules do
selectively reabsorbs nutrients.
what do the distal con tubules do
control ph of blood
what does loop of henle do
reaborbs water
Movement of fluids from the glomerulus to glo capsule is due to
pressure filtration
where does tubular excretion occur
distal tubules
where does tubular absorption occur
proximal tubules
