small anastomoses
|
|
obstruction of liver =>
|
blood shunted to IVC
- **bypasses liver** |
|
***overuse of small anastomoses =>
|
inflammation => internal hemorrhoids
|
|
lymph drainage of GI tract =
(3) |
celiac, superior mesentery, and inferior mesentery nodes
|
|
ductus venosus:
(2) |
1. bypassed liver
2. becomes ligamentum venosum after birth |
|
umbilical vein becomes:
|
ligamentum teres hepatis
|
|
ductus arteriosus bypasses:
|
the lungs
|
|
which arteries supply the inferior of the diaphragm?
|
the inferior phrenic arteries
|
|
****structures passing through diapragm:****
(3) |
1. IVC / right phrenic nerve (T8)
2. Esophagus / ant. and post. vagal trunks (T10) 3. Aorta / thoracic duct / azygos vein (T12) |
|
kidneys:
(4) |
1. located T12-L3
2. around ribs 11 and 12 3. right kidney is lower 4. retroperitoneal |
|
layers of kidneys: outside =>
|
pararenal fat => renal fascia => perirenal fat covering kidneys
|
|
polycystic kidney disease:
(3) |
1. replacement of renal tissue with cysts on both
2. AD inheritance 3. blood in urine and HTN until progressive renal failure |
|
hydronephrosis =
|
progressive dilation of renal calyces => big holes
|
|
hydronephrosis is caused by:
|
urinary tract obstruction
|
|
pelvic kidney =
|
one fails to ascend due to obstruction by IMA
|
|
horse-shoe kidneys =
|
both fuse and don't ascend
|
|
renal cell carcinoma:
(2) |
1. most common renal malignancy
2. men, 50-70 |
|
ureters transport:
|
urine form kidneys to bladder
|
|
**suprarenal / adrenal glands are supplied by:
(3) |
superior, middle, and inferior renal arteries
|
|
adrenal glands are drained by:
(2) |
the right and left suprarenal veins
|
|
abdominal aorta:
(2) |
1. from T12 to L4
2. terminates as common iliacs |
|
Abdominal Aortic Aneurysms are a result of:
(4) |
1. athero
2. HTN 3. wound 4. infections |
|
***the IVC returns blood from ___________ except for _______***
|
below the diaphragm;
blood from the gut |
|
****structures on the left side of the body use ______ to get to the ____****
|
left renal vein;
IVC |
|
portal veins => liver =>
|
hepatic veins => IVC
|
|
colon cancer imaging ~
|
apple core
|
|
the accessory hemizygos vein joins the azygos at:
|
T7
|
|
4 branches of SMA =
|
1. middle colic
2. right colic 3. iliocoli 4. jejunal and ileal branches |
|
3 branches of IMA =
|
1. left colic
2. sigmoidal branch 3. superior rectal branch |
