TMA Veins Flashcards
what are the tributaries of the portal vein and which are the main ones
Main Superior mesenteric vein Splenic vein But also The right and left gastric Paraumbilical veins Cystic vein
the cystic vein drains which organ
the gallbladder
the paraumbilical veins drain what
the skin of the umbilical region
The right and left gastric veins drain what
the stomach
The splenic vein is formed from a variety of smaller/larger vessels as they leave the _ of the spleen.
smaller
hilium
Unlike the splenic artery, the splenic vein is straight/curved and it does/doesnt maintains contact with the _ of the pancreas as it crosses the _abdominal wall. As the spleninc vein crosses the _ of the pancreas it joins the superior mesenteric vein to form what
straight does body posterior neck portal vein
what type of blood does the portal vein carry and where does it take this blood to?
venous blood that has nutrients that has been taken from food
the blood goes to the liver for processing
the main vessel of the portal system is whiich vein?
the portal vein
the portal vein is formed from the convergence of the which organs
spleen
pancrease
gallbladder
abdo part of the GI tract
which two veins form the portal vein and where
portal vein is formed by the splenic and SM at level L2 anterior to the neck of the pancreas
path of the portal vein as the portal vein ascends it passes
_ to the _ and _ and immediately before entering the liver it splits into left and right with each entering the parencyma of the liver seperately

what are the main tributaries of the spleninc vein
the pancreatic
the short gastic
left gastroomental
inferior mesenteric
Short gastric veins drain
drain the fundus of the stomach.
Left gastro-omental vein drains
the greater curvature of the stomach.
Pancreatic veins drain
the pancreas
Inferior mesenteric vein drains
drains the splenic flexture desceding sigmoid and rectum
tributaris of the IM
left coelic and sigmoid veins
path of the IM, The iM starts at the _ vein and as it ascends it get tributatries from _ and _. as it ascednds further passing _ to _ of the pancrease it mostly then goes to join the splenic vein
The iM starts athte superior renal vein and as it ascends it get tributatries from left coelic and sigmoid veins. as it ascednds further passing posteiror to the body of the pancrease it mostly then goes to join the splenic vein
The superior mesenteric vein drains blood
from the small intestine, cecum, ascending colon and transverse colon
journey of SM
starts at the mesentery of the small intestine asending posterior to the neck of the pancreas to join the splenic vein
SM iis formed by a convergence veins draining where
terminal iliac caecum and appendicular veins
tributalies of the SM are
ilial jejunal ileocolic middle colic right colic ant post inf pancreacticduodenal right gastro oamental
ileal vein drains

pancrease and duodenum
ileo coelic vein drains
ileum colon and secum
right colic vein drains
aseinding colon
middle colic drains
transverse colon
Many of these tributaries are formed as an accompanying vein for _ the superior mesenteric artery
each branch of
the systemic venous system transports blood to the
_ atrium of the heart and the major vessel involved is the _
right
IVC
location of the IVC is from
all structures below the diaphragm.
location of the Inferior vena cava
on the posterior abdominal wall right of the aorta and anterior to the verterbral spinal colum
course of the IVC
starts at the convergence of the common iliacs at L5 then ascends pieecing the tendon of the diaphragm passing through the T8 caval hiatus and emptying into teh right atria
• During its long course, the inferior vena cava shares an anatomical relationship with numerous abdominal structure
the right common iliac artery, the root of the mesentery, the head of the pancreas, the bile duct, the portal vein and the liver.
where do the left adrenal and testicular veins empty into?
left renal vein
There are no tributaries from the _ as these structures are first drained into _. However, venous return from these structures ultimately enters the inferior vena cava via the _(after being processed by the liver).
