GMS6401 Renal Exam Questions And Correct Answersgeneral Function of a kidney - Answer 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 - Answer makes glucose, bicarbonate, renin, erythroppoetin
and D3
basic renal processes - Answer 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 - Answer 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 - Answer before and after it, afferent and
efferent arterioles
renal corpuscle - Answer 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 - Answer adrenal gland lies above, retroperitoneal and encased in fat
blood supply of kidney - Answer 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

gross structure of kidneys: in a sagittal section (cut right down the middle) - Answer
cortex and medulla (pyramids)
Drainage system: - Answer renal pyramid to minar calyce to major calyce to renal pelvis
to ureter to bladder to urethra
How does renal tubule epithelium facilitate transport in the tubule - Answer form a
cylinder and are joined by tight junctions, Na+/K+ ATPase are located on the outside of
the epithelial cells , in the luminal surface there is no ATPase pump so Na+ is absorbed
and there is unidirectional transport from lumen into peritubular space for NA+ to be
reabsorbed
list different tubule segments: superficial glomeruli - Answer bowmans capsule, proximal
convoluted tubule in cortex, Proximal straight tubule, descending limb of loop of henle in
