Kidney anatomy

Renal artery

Supplies blood

Renal vein

Carries unfiltered blood out

Fibrous capsule

surrounds entire organ

Perirenal fat

cushions to resist impact at abdominal wall; no ribs to protect kidneys

Cortex

Where filtration takes place, lightly colored, periphery of organ

Medulla

interior of kidney, made up of renal pyramids; disconnected but connected by calyx

Minor calyx

apex of renal pyramid, connects pyramids to major calyx

Major calyx

Larger cavitity that dumps into renal pelvis

Renal pelvis

Connecting point of major calyx and ureter to head to urinary bladder

Ureter histology

cute pink ombre aura with a snowflake in the middle, outermost being smooth muscle, then the lamina propria (connective tissue) and then transitional epithelium

Muscular layer of ureter

Almost always squeezed tight to prevent backflow from the bladder or anywhere in the urinary tract back into the kidney

Urinary bladder histology

Purple and squiggly, transitional epithelia, lamina propria, smooth muscle

Renal cortex glomerulus histology

purple nuclei, magenta other shit, big fat glob somewhere (glomerulus) and ovular lumens surrounded by cuboidal epithelium (renal tubes/PCT & DCT)

glomerulus histology

big fat thing with stuff twisted around in there, nuclei in there are PODOCYTES, cuboidal epithelia with nuclei around ovular lumen = PCT, red circle = afferent arteriole

Renal medulla

pink circles, collecting ducts are largest, thick/ascending segments are medium, thin/descending segments are smallest
