Flashcards in Gastrointestinal Tract II Deck (53):
1

Which mesentary is names 'the mesentary'?

That which connects the jejunum and ileum to the abdominal wall

2

Is the liver intra- or retroperitoneal?

Intraperitoneal

3

Which is the largest solid viscus?

The liver

4

In which quadrant is the liver located?

Mainly in the upper right quadrant

5

Main functions of th eliver
1)
2)
3)

1) Bile production
2) Filter blood
3) Metabolisms

6

Surfaces of the liver

Diaphragmatic surface
Visceral surface

7

Qualities of the hepatic diaphragmatic surface

Smooth
Superior and anterior

8

Qualities of the hepatic visceral surface

Concave
Inferior and posterior

9

Number of hepatic lobes

Two

10

What divides the hepatic lobes?

The falciform ligament

11

Qualities of the inferior border of the liver

Sharp surface

12

Structures on the visceral side of the liver

1) Groove in which inferior vena cava and gallbladder sit
2) Hilum (or portal hepatis)

13

Structures making up portal hepatis

1) Hepatic duct
2) Hepatic artery
3) Portal vein

14

Constituents of the hepatic triad

1) Hepatic duct
2) Hepatic artery
3) Portal vein

15

Point of entry of hepatic traid

Portal hepatis (Hilum)

16

Role of hepatic duct

Drains bile from the liver

17

Role of portal vein

Brings venous blood form the GIT and abdomen into the liver for metabolism

18

Structures dividing the anatomical lobes of the liver

1) Falciform ligament
2) Venosum ligament

19

Names of hepatic accessory lobes

1) Caudate lobe
2) Quadrate lobe

20

Anatomical lobe containing accessory hepatic lobes

Right anatomical lobe

21

Hepatic sagittal fissures

Left = Ligament venosum
Right = Gallbladder and IVC groove

22

What makes up the hepatic left sagittal fissure?

Ligament venosum

23

What makes up the hepatic right sagittal fissure?

Groove for the gallbladder and IVC

24

Structures delineating the hepatic accessory lobes

1) Left, right sagittal fissures
2) Hilum

25

Location of the gallbladder

Sits on the anterior visceral surface of liver

26

Three parts of gallbladder

Fundus, body, neck

27

Duct linking gallbladder with the common bile duct

Cystic duct

28

Quadrant of the pancreas

Upper left quadrant

29

Is the pancreas retro- or intraperitoneal?

Retroperitoneal

30

Parts of the pancreas
1)
2)
3)
4)

1) Head
2) Neck
3) Body
4) Tail

31

Location of pancreatic head

Surrounded by duodenal curve
Attached to descending and transverse duodenum

32

Location of pancreatic tail

Closely related to hilum of spleen
Anterior to left kidney

33

Functions of pancreas

Endocrine and exocrine

34

Endocrine functions of pancreas

Secrete into blood (many small blood vessels in pancreas)

35

Exocrine functions of pancreas

Secrete into main pancreatic duct and accessory pancreatic duct into duodenum

Main pancreatic duct+common bile duct --> Major duodenal papilla

Accessory pancreatic duct --> Minor duodenal papilla

36

Quadrant of spleen

Left upper quadrant

37

Ribs against which the spleen rests

9, 10, 11

38

Danger of breaking ribs 9, 10 or 11

Jagged ends can damage splanchnic artery
Heavy bleeding into peritoneal cavity

39

Path of aorta

1) Descends through thorax, penetrates diaphragm at T12
2) Splits into common iliac arteries at L4
3) Unpaired branches supply unpaired viscera

40

Aortic branches supplying the gut

Celiac trunk (foregut), superior mesenteric artery (midgut), inferior mesenteric artery (hindgut)

41

Structures on anterior aorta

Unpaired branches supplying unpaired viscera
- Celiac trunk, superior/inferior mesenteric arteries
Abdominal aorta has paired branches supplying viscera and abdominal walls
- Renal arteries, suprarenal arteries, testicular/ovarian arteries

42

Paired arteries of anterior abdominal aorta

Renal arteries, suprarenal arteries, testicular/ovarian arteries

43

Structures on posterior aorta

Only paired arteries (parietal arteries)
Phrenic arteries

44

Foregut

Begins at abdominal oesophagus
Ends between inferior and superior duodenal papilla

45

Midgut

Begins inferior to major duodenal papilla
Ends at distal third of transverse colon

46

Hindgut

Begins just before left colic flexure (splenic flexure)
Ends mid anal canal

47

Celiac trunk branches

Branches directly to pancreas, duodenum (before major duodenal papilla)

48

Superior/Inferior mesenteric artery

Branch directly to the retroperitoneal duodenum, distal third of transverse colon, descending colon, rectum, anal canal

Supplies intraperitoneal jejunum, ileum, sigmoid colon through mesentary

49

Way that paired viscera drain blood to IVC

DIrectly

50

Way that unpaired viscera (except liver) drain to IVC

Via portal system

51

Venous drainage of peritoneal unpaired viscera

Unpaired GIT --> Portal vein --> Hepatic veins --> IVC --> Right atrium

52

Venous drainage of liver

Directly to IVC via hepatic veins

53

Veins normally forming portal vein

Superior mesenteric vein and splenic vein
