Flashcards in Abdominal Cavity Deck (26):
1

Upper Qudarant

L quadrant:
Stomach and Spleen
R. Quadrant:
Liver and extends to the left

2

Lower Quadrants

R. Quadrant:
large intestine

3

Passage of food

Pharynx -> esophagus-> stomach -> Duodenum -> Jejunum -> ileum -> ileocecal valve -> cecum -> ascending colon -> right colic flexure -> transverse colon -> left colic flexure -> descending colon -> sigmoid colon -> rectum -> anus

4

Cardiac Orifice

Esophagus enters the stomach
Weak sphincter which allows the passage of air (burp) and sometimes acid

5

Fundus

Accumulates swallowed air

6

Body of the stomach

J- Shaped
Many shapes and sizes

7

Lesser Curvature of the Stomach

Continues with the right edge of the esophagus

8

Greater Curvature

Inferior border of the stomach

9

Pylorus

Narrow region of the stomach that leads to the small intestine

10

Plyoric Sphincter

Smooth muscle
Guards btw the stomach and the small intestine

11

Falciform Ligament

Fold of the peritoneum that extends from the liver to the diaphragm and the anterior abdominal wall
Divides the right and left lob of the liver

12

Round ligament (Ligamentum Teres)

The free edge of the falciform ligament, rod of the connective tissue
Remnant of the umbilical vein

13

Fundus of the gall bladder

Peaking out from under the right lobe of the liver
responsible for the storage and subsequent release of bile produced by the liver.

14

Greater Omentum

Attached to the greater curvature of the stomach
Extends over the coils of the intestine (Apron)
Rich blood supply and ample lymphatics

15

Small intestine

Duodenum, Jejunum and Ileum

16

Ileocecal vlve

Smooth muscle
Where the small intestine empties into the large intestine

17

Cecum

Sac like, the start of the large intestine
attached is the vermiform appendix

18

Ascending Colon

Right abdominal wall

19

Right colic flexure

Hepatic flexure
Large intestine makes a sharp turn at the liver

20

Transverse Colon

Crosses the abdominal cavity
Suspended by the greater omentum

21

Left colic flexure

Splenic flexure
Sharp turn down

22

Descending colon

Passes along the left abdominal wall

23

Sigmoid Colon

S-shaped structure
Allows the colon to go to midline

24

Rectum

End of the line
posterior to the urinary bladder

25

Rugae

Folds of the stomach
As more substance goes it these stretch

26

Duodenum

"12 Fingers"
