kidneys primary functions filtration, reabsorption, secretion and excretion
1. Filters the blood of waste; develops a concentrated urine
excretion does what 3 things 2. Eliminates waste: electrolytes, metabolites,and nitrogenous compounds
3.Maintains acid-base balance: H+ secretion, HCO3- reabsorption
excretion filters the ___ of waste and blood, concentrated
develops _____________________
excretion eliminates __________ like __ , waste: electrolytes, metabolites, and nitrogenous compounds
____________ and ____________
excretions maintains _______________ like acid-base balance: H+ secretion, HCO3- reabsorption
_________ and ___________
1. Synthesizes the active form of vitamin D
secretion does what 3 things in 2. Secretes renin to activate RAAS
kidney 3. Secretes erythropoietin to stimulate erythropoiesis
secretion synthezises the active vitamin D
form of
_________
secretion secretes to activate renin to activate RAAS
___________
secretion secretes to stimulate erythropoietin to stimulate erythropoiesis
_______________
nephron is the basic unit of the kidney
nephron is a sequence of that filter tubes that filter blood of waste and conserve the fluids and electrolytes
what
Glomerular Filtration Rate (GFR) is The renal blood filtered per unit of time
what does GFR measure kidney function
GFR is directly related to renal perfusion
what causes decrease GFR decreased renal perfusion and blood pressure
, how can GFR be measured serum creatinine clearance
kidneys release EPO in response to low oxygen levels a stimulates the
RBC production how?
synthesis and maturation of erythrocytes.
In response to low renal perfusion, kidneys secrete renin à activates
Control of Blood Pressure
RAAS (Renin Angiotensin Aldosterone System)
in response to low renal perfusion renin, RAAS
kidneys secrete ________ which will
activate _________
ADH is released in reponse to hypertonicity of plasma
ADH increased reabsorption of and h20 and vasoconstriction
potent ________
aldosterone retain _ in exchange for na+ in exchnage for k+ loss
________
aldosterone is reguated by ___ and angiotension II and potassium
____________
Atrial Natriuretic Peptide secreted atria in reponse to high blood volume this also increases GFR
from
_________ in response to __ and this
increases
Atrial Natriuretic Peptide decreases Decrease Na+ reabsorption & inhibits renin secretion
____________ and inhibits
_______________
• Normal GFR
• Water regulated
When Kidneys Function we see (4)
• Fluid, electrolyte, and pH balance regulated
• Nitrogenouscompounds excreted
• Decreased GFR
• Less waste is removed; more waste remains in blood
When Kidneys fail we see (4)
• Unable to regulate fluid, electrolyte, and pH balance
• Nitrogenous compounds build up in the blood
Nitrogenous compounds build up • BUN: Blood urea nitrogen
in the blood what 2 things • Creatinine
Prerenal Dysfunction is Blood supply decreased
Prerenal Dysfunction we see (3) shock, dehydration, vasoconstricition
Intrarenal Dysfunction is Kidney tubule function decreased
Intrarenal Dysfunction we see (3) Ischemia, toxins, intratubular obstruction
postrenal dysfunction is urine flow blocked
postrenal dysfunction we see (3) stones, tumors, enlarged prostate
1. Hypotension, hypovolemia, heart failure decreased cardiac output
2. ↓renal blood volume
describe the 5 steps in prerenal
3. ↓ glomerular capillary hydrostatic pr.
dysfunction
4. ↓ GFR
↑BUN, Cr. (wasteproduct)↓ Urine output (oliguria, auria)
5.
intrarenal dysfunction is Damage to renal structure (glomerulus, tubule, interstitium)
