Kidney Gross Anatomy- Ewww You're in for fun with Urine production

Kidney terms to know:
Hilium (hilius)- renal artery, vein and ureter enter/leave kidney
Renal Capsule- smooth transport membrane that adheres tightly to external aspect of kidney
Cortex- Superficial kidney layer- lighter in color and full of Bowman's capsules
Medulla- Deep to cortex, darker red/brown holds loops of henle
Medullary pyramids- triangular and striated sections, base facing cortex
papilla (apex)- points to inner kidney
kidney model

Renal Columns- area of cortex which dips between pyramids
Renal Pelvis- Medial to hilus, relatively flat/basin-like cavity w/ ureter
Major Calyx- large external of renal pelvis
Minor Calyx- subdivision of major calyx
Renal Artery/Vein- branches 5x's as it enters the kidney it becomes --->
Segmental Arteries- enter hilus it becomes --->
Lobar Arteries- it becomes --->
Interlobar Arteries-
Aracate Arteries- at top of medullary region, these curve over base of medullary pyramid
Interlobular Arteries- ascend into cortex giving off--->
Afferent Arterioles
