Renal Anatomy - Kidney Flashcards
4 main functions of kidney
filter blood waste products
maintain electrolyte homeostasis
control BP
produce hormones that regulate RBC production (erythropoietin)
where are kidneys located
between T12-L3
which kidney is higher up
left kidney (liver pushes right kidney down)
at what level of the spinal cord is the hilum located
L2
kidneys are covered by what muscle group
erector spinae muscle group
3 main region of the kidney
cortex
medulla
pelvis
where does the collecting system begin
renal pelvis
What portion is the outer portion and which is the inner portion
cortex = outer
medulla = inner
what does the cortex contain
glomeruli
convoluted tubules
what does the medulla contain
pyramids
renal papillae
major and minor calices
renal pelvis
what is found within pyramids
collecting ducts
vasa recta (peritubular capillaries)
what is between each pyramid
renal column
where do kidney stones commonly lodge
ureteropelvic junction
ureterovesicular junction
brim of the iliac crest
outermost tissue layer surrounding kidney
renal fascia (or perirenal fascia)
middle tissue layer covering kidney
perirenal fat
innermost tissue covering kidney
renal capsule
function of perirenal fat
structure/support for renal vessels
protects kidney from trauma
what does kidney share blood supply with
adrenal gland
primary blood supply to kidney
renal artery
venous drainage of kidney
renal vein
additional blood supply of adrenal gland
inferior adrenal artery
middle adrenal artery
superior adrenal artery
inferior adrenal artery branches from
renal artery
middle adrenal artery branches from
abdominal aorta
superior adrenal artery branches from
inferior phrenic artery
