Whoa!? No no no, it's a joke 55
Today I so serious because the examination will coming soon.
Urinary system have 4 structure = Kidney+Ureter+Urinary Bladder+Urethra -> KUB
Superior urinary organs = Kidney + Ureter
Inferior urinary organs = Urinary Bladder + Urethra
I will focus only the superior urinary organs.
Superior urinary organs are retroperitoneal structure (only have peritoneum
on their anterior side). And them lie on posterior abdominal wall.
Kidney
[A structure of kidney]
Human has bilateral kidney.It's red-brown color and kidney bean shaped.The size is around 10x5x2.5 cm.
blood supply = by renal artery (branch of abdominal aorta) and renal artery is separate to 5 segmental artery.
Summary : abdominal aorta -> renal artery -> segmental artery
-> lobar artery -> interlobar artery -> arcuate artery
-> interlobular artery -> afferent glomerular arteriole
Ureter
Ureter is a muscular tube. It links between a kidney and a urinary bladder.
Ureter has a narrow site 3 place
1. between renal pelvis and ureter
2. When ureter overlaying pelvic brim
3. when ureter going inside the urinary bladder
Them is the site that maybe obstruct by ureteric stone.
[A narrow site of ureter]
blood supply = superior supply by renal artery
middle supply by testicular / ovarian artery
inferior supply by superior vesicular artery
Suprarenal gland
It's lie on upper pole of kidney(superomedial). In the right side, It's pyramid shaped because pushed by the liver. In the left side, It's semilunar shaped.
blood supply = superior suprarenal artery
middle suprarenal artery
inferior suprarenal artery
Whoopee! yeh yeh! finished finish
1 lessonnnn [all of 31 (TT^TT )]
I don't detail for this story because it not easy to understand
(Er.. or I am stupid 55)
So I think this article will be useful for you.
