GMS 6401 RENAL QUESTIONS & ANSWERS
General Function of a kidney - Answers - 1) controls volume and compos. Of body
fluids
2)excretes wastes/ drugs
3)makes glucose, bicarbonate, renin, erythroppoetin and D3
What does the kidney make - Answers - makes glucose, bicarbonate, renin,
erythroppoetin and D3
Basic renal processes - Answers - 1)filters plasma
2)secreted from peritubular blood into tubule
3) reabsorbs solutes/ water
Excess is then excreted
Different cell types that form the glomerulus - Answers - Anatomy is unique:
Mesangial cells- the central core, contractile cell
Endothelial cells- fenestrated, (gapped) lie on glomerular basement membrane
Podocyte- lies on outside of endothelial cells, form pores
Granular cells- in afferent arteriole, secrete renin
The golumerulus has resistance vessels both - Answers - before and after it, afferent
and efferent arterioles
Renal corpuscle - Answers - The glomerular capillary is surrounded by the Bowmans
capsule, epithelial cells that marks the beginning of the tubule and water and solutes in
plasma are forced acrossed capillary wall and create filtration
Location of kidneys - Answers - adrenal gland lies above, retroperitoneal and encased
in fat
Blood supply of kidney - Answers - To: abdominal aorta to the renal artery to
segmental arteries to interlobar arteries to arcuate arteries to the cortical radial artery,
afferent arteriole, glomerular capillaries and then efferent arteriole
From: renal vein to vena cava
All glomeruli are located in - Answers - the cortex
A nephron is a - Answers - glomerulus and a tubule
Two types of glomeruli - Answers - 1) cortical, in outer 2/3rds, about 90%
2) juxtamedullary, in inner 1/3, anout 10%
Micturition is - Answers - voluntary
