Q

Where does bile travel?

A

Travels down the COMMON HEPATIC DUCT which runs with the proper hepatic artery and portal vein in the lesser omentum (STILL IN LIVER)

Then joins with the CYSTIC DUCT from the gallbadder to form the BILE DUCT

Bile duct descends until it meets the MAIN PANCREATIC DUCT and empties into the major duodenal papilla at the AMPULLA OF VATER

A

Lies posterior to the stomach between the spleen and duodenum

  • Head: within the C of the duodenum
  • Unicinate Process: projects from the lower part of the head
  • Neck: ant to superior mesenteric vessels
  • Body: elongates from neck to tail

Q

Major Pancreatic Duct

A

begins at the tail, passes through the body and joins the bile duct in the lower part of the head

-forms HEPATOPANCREATIC AMPULLA (of VATER)

  • enters the descending 2nd part of the duodenum at the MAJOR DUODENAL PAPILLA
    • Surrounded by SPHINCTER OF AMPULLA (of ODDI)

25
Accessory Pancreatic Duct
Empties into Minor Duodenal Papillae | -branches and enters duodenum superior to major papilla
26
Arterial Supply to Pancreas
- Gastroduodenal Artery - Inferiorpancreaticoduodenal Artery (from SMA) - Dorsal Pancreatic Artery - Great Pancreatic Artery
27
Gastroduodenal Artery
From common hepatic from celiac trunk - Anterior superior pancreaticoduodeunal artery - Posterior superior pancreaticoduodenal artery
28
Inferiorpancreaticoduodenal Artery (from SMA)
- Anterior inferior pancreaticoduodenal artery | - Posterior Inferior pancreaticoduodenal artery
29
Dorsal Pancreatic Artery
From inferior pancreaticartery and splenic artery
30
Great Pancreatic Artery
From inferior pancreatic artery and splenic artery
31
Spleen
In the left hypochondrium | -lies against the diaphragm near ribs 9 and 10
32
Spleen Connected to
Greater curvature of stomach via GASTROSPLENIC LIGAMENT | -Left kidney via SPLENORENAL LIGAMENT
33
What ligaments are part of the greater omentum?
- Gastrosplenic Ligament | - Splenorenal Ligament
34
Splenic Hilum
Entry point of SPLENIC ARTERY (branch off of celiav trunk) | -Exit point for splenic vein
35
Superior Mesenteric Artery Syndrome
High pressure in SMA enlarges it and presses down on it and blocks/hinders digestions -smashes 3rd part of duodenum becuase of dilation
36
Nutcracker
SMA curshes renal vein with aorta
37
The Portal Circulation allows blood from where, to travel into the liver before entering the IVC
Digestive tract (abdominal esophagus to superior rectum), spleen, pancreas and gall bladder
38
Blood passes through the liver for processing and empties into the IVC through the _____
Heptatic Veins
39
Do all portions of organs drain into the portal circulation?
NO
40
Another name for Portal System
Hepatic portal system
41
DIfference between Hepatic Portal Veins and Hepatic Veins
Hepatic Portal Vein: drains all organs into liver | Hepatic Vein: drains from liver to IVC
42
Portal System is a secondary capillary bed in system- Why?
Arteries drain to first capillary bed - then thru a portal vein, we travel to a 2nd capillary bed - second bed then gets drained by veins
43
In Portal System: First set of capillary beds are within organs that are draining (primary capillary plexus-actually in digestive organs)-- all digestive organs are drained via ____
Hepatic portal veins
44
Hepatic bein drains into second capillary plexus (within the liver itself)- liver contains sinuses/sinusoidal secondaries. This is where detoxyfying occurs- once clean, it drains via blood into _____
IVC
45
Does the hepatic portal system occur anywhere else in the body?
Yes, in the brain but for a different function- not filtration!
46
Portal Circulation
-Special circulation that drains most digestive organs
47
What drains into the portal vein?
Venous vessels draining structured supplied by the celiac, SMA, and IMA
48
Portal Vein divides into sinusoids in the liver that drain into ___
Hepatic veins into the IVC
49
Describe how the inferior mesenteric vein drains
Drains up into splenic since crossing over would have to cross high pressured aorta
50
Portal Vein Drainage
- Left gastric vein - Splenic vein - Superior mesenteric vein
51
Splenic vein branches to...
- Short gastric veins - left gastro-omental veins - pancreatic veins - inferior mesenteric veins: WHICH DRAIN TO--- Left colic vein, Sigmoid vein, superior rectal vein
52
Superior mesenteric vein branches to...
- Jejunal ileal, iliocolic, right colic, middle colic vein - Right gastro-omental vein - Anterior and posterior pancreaticoduodenal vein
53
Anastomosis
Connection between structures | -places where vlood will directly enter the systemic circulation instead of passing through the portal system
54
What are the 3 places where the portal circulation anastomose with the system circulation>
1. Esophagus- Azygous vein 2. Inferior Rectum/Anus- middle and inferior rectal veins 3. Paraumbilical Area-Veins on Anterior abdominal wall
55
What drains Upper part of esophagus
Azygous vein/system-which then goes to SVC (systemic)
56
What drains Lower part of esophagus (abdominal part)?
Portal circulation (portal)
57
What drains superior rectum?
Portal Circulation (portal)
58
What drains middle and inferior rectum?
Iliac veins- which merge to make IVC (systemic)
59
Concequences of alcoholics having a fatty/compressed liver
The creation of portal hypertention that backs everything up-cannot drain structures via portal ciculation and everything thats supposed to be drains gets pushed and stopped.
60
When does drainage of a whole organ go thru systemic circulation?
When theres alocholic/fatty liver since they can reach portal- this is not meant to happen so blood vessels get engorged and its a problem (esophageal vericies)- when you ear you burst them and throw up blood since azygous system (PORTAL) is clogged
61
Caput Medusae
Engorgemnet of veins in umbelical region bc systemic drainage is being asked to do TOO MUCH since portal circulation is doing too much
62
Lymphatics of portal system
Drainage via pre-aortic lymph nodes - celiac - superior mesenteric - inferior mesenteric
63
All lympahtics for portal system drain into...
Cisterna Chyli
64
What are the 4 options from sypathetic innervation?
1. Leave spinal cord via ventral root 2. Enter sympathetic trunk via white ramus (NO SYNAPSE) 3. Via Splanchnic Nerve- goes to another ganglion (for the most part, sympathetic ganglion are located along aorta, Parasymapthetic ganglion are located on or within target organ) Synapse with sympathetic ganglion then synapse and a postganglion which will travel to effector to exert sympathtetic effect
