1.1 Anatomy Flashcards
what level is the hilum?
L1
compare length of renal arteries, and renal veins
right renal artery longer, as it has to loop behind IVC
left renal vein longer, as it goes in front of aorta
2 types of nephron, and their amounts
85% cortical
15% juxtamedullary
why is juxtamedullary LoH longer?
concentrates urine by removing more water
function of bowman’s capsule
collects the fluid that exits capillaries
peritubular capillaries
surround the nephron, helping to absorb Na+/Cl-/H2O
vesa recta
-straight arterioles around LoH in juxtamedullary nephrons, then become straight veins
-reach the medulla
macula densa cells
-sense fluid composition in DCT
-affect BP
extraglomerular mesangial cells
transmit message from macula dense to granular cells
granular cells
release renin in response to macula dense cells
what prevents kidneys moving up any higher in development?
superior mesenteric artery
where do L and R gonadal veins drain into?
R- IVC
L- renal vein
how many people have >1 renal vein?
25%
sign of tumour blocking L gonadal vein
worm appearance swelling of testes, as tumour from L renal vein extends to block L gonadal vein
order the arteries supplying kidneys
-abdominal aorta
-renal artery
-segmental artery
-interlobar artery
-arcuate artery
-interlobular artery
-afferent arteriole
-glomerulus
-efferent arteriole
-peritubular capillaries/ vasa recta
