What are the organs of the urinary system??

Bladder (urinary tract)
– single tube for elimination out of bladder
Urethra (urinary tract)

The kidney (nephrose) are located on ?
around T12 and L3 vertebrae
L kidney is slightly superior to the R kidney due to the presence of the __ ?
Liver
Kidneys are held in place at the abdominal cavity due to:
-Overlying peritoneum
-Contact with adjacent visceral organs
What are the 3 types of connective tissue of the kidneys?
Fibrous capsule, Perinephric fat, and Renal Fascia
a layer of collagen fibers that covers the outer surface of the entire organ
Fibrous capsule
a cushioning layer of adipose tissue surround each fibrous capsule
Perinephric fat
a dense fibrous outer layer that anchors the kidney to surrounding structures
Renal Fascia
an internal cavity within the kidney that the fibrous capsule covers
Renal sinus
The_____is bound to the outer surfaces of the structures which aids in stabilizing the ureter, blood vessels, and nerves
Renal capsule
most superficial portion of kidney and connects with the fibrous capsule
Renal cortex
consists of 6-8 “renal pyramids”. The base of each pyramid touches the cortex and tip (renal papilla) projects into the renal sinus
Renal Medulla
____lie in-between pyramids
Renal columns
