1. calculate the to- ~1kg= 2.20 lbs
tal body weight ~convert 145 lbs into kg
for a person ~1kg/x = 2.2lbs/145lbs
the weights 145 ~65.90 kg
pounds ~65.90 kg x 0.60 = 39.54 L
~39.54L
2. What are the ~regulate plasmic ionic composition
functions of the ~regulate plasma volume
kidney? ~regulate plasma osmolarity
~regulate pH
~remove metabolic waste products and foreign sub-
stances from plasma
~endocrine functions
3. what are they Renin: regulate BP
kidney endocrine Erthropoietin: regulate RBC production
functions?
4. The two types of ~Cortical nephron -----> peritublar capillary
nephrons are ~Juxtamedullary nephron-------> vasa recta capillary
5. Trace the path of 1)Capsule
filtration 2)PCT
3)descending limb
4)loop of henle
5)ascending limb
6)DCT
7)collecting duct
8)renal papilla
6. What is the renal glomerulus + Bowman's capsule
corpuscle?
7. what is the podocytes wrap around the fenestrated holes so that it
function of can be perfect size in order to keep the RBC and proteins
podocytes? inside
8. RBC's

what does not
get filtered out of
the glomerulus?
9. Which portion of Descending limb: water permeable
the nephron is
water permeable Ascending limb: water impermeable (solute permeable)
and which por-
tion in water im-
permeable
10. what substances 100% reabsorption of glucose/amino acid
are fully reab-
sorbed in the this is because you NEVER pee out glucose or amino acid
PCT? what is
the purpose of
this full reab-
sorption?
11. If glomerular fil- substances cannot be absorbed quickly enough and are
tration rate is too lost in the urine
high
12. If glomerular fil- everything is reabsorbed, including wastes that are nor-
tration rate is too mally disposed of
low
13. juxtaglomerular macula densa cells + juxtaglomerular cells(secrete renin)
apparatus =
14. What is the func- responsible for sensing BP in the kidney, the amount of
tion of juxta- Na+ and K+
glomerular appa-
ratus?
15. urea recycling 1- part of the uric acid that is expelled out of the collecting
and countercur- duct gets excreted out as urine and part of it gets into
rent multiplier nephron
mechanism
2- Ions from the uric acid goes into latter part of the
2/6
