Nephron physiology 1

Question 1

where will we have pain if stone in ureteropelvic junction

Answer 1

flank pain

Question 2

where will we have pain if stone near iliac vessels/pelvic brim

Answer 2

groin and anterior thigh (L1-L2)

Question 3

most common type of nephron

Answer 3

cortical (85%)

Question 4

cortical nephron

Answer 4

contain most of the renin
role in reabsorption of water and filtration of solutes
larger role in systemic blood pressure and more stimulation by systemic NC

Question 5

juxtamedullary nephron

Answer 5

larger role in concentrating urine due to osmotic gradients by going deeper in the medulla

Question 6

renal corpuscle

Answer 6

glomerulus + bowman’s capsule

Question 7

mesangial cells in glomerulus

Answer 7

removes debris and proteins in the basement membrane
contractile and aids with vascular permeability

Question 8

filtration equation

Answer 8

(capillary hydrostatic + bowman’s oncotic) - (capillary oncotic + bowman’s hydrostatic)

Question 9

forces favoring filtration

Answer 9

capillary hydrostatic
bowman’s oncotic

Question 10

forces opposing filtration

Answer 10

capillary oncotic
bowman’s hydrostatic

Question 11

creatinine

Answer 11

endogenous substance that is freely filtered
