portion of the pylorus that connects to the body of the stomach

Front 14

pyloric antrum

Back 14

connection between the stomach and the small intestines

Front 15

pyloric sphincter

Back 15

ring of muscle that protects the opening between the stomach and the duodenum

Front 16

small intestines

Back 16

20 ft canal extending from the pyloric sphincter to the large intestine

wider canal of about 5 ft in length that extends from the ileum to the anus

cecum

Back 21

u-shaped pouch that is the first portion of the large intestine

Front 22

colon

Back 22

Has 4 parts: ascending, transverse, descending, sigmoid

Front 23

ascending colon

Back 23

travels upwards from the cecum to the undersurface of the liver

Front 24

transverse colon

Back 24

passes horizontally from right to left towards the spleen

Front 25

descending colon

Back 25

travels down the left side of the abdominal cavity to the sigmoid colon

Front 26

sigmoid colon

Back 26

continues from the descending colon above and joins the rectum below

Front 27

rectum

Back 27

last division of the large intestine, ends at the anus

Front 28

anus

Back 28

lower opening of the digestive tract, controlled by two anal sphincter muscles

Front 29

salivary glands

Back 29

produce saliva which flows into the mouth

Front 30

liver

Back 30

1.Secretes bile, a digestive juice containing enymes that break down fat.
2.Produces bilirubin through the desctruction of hemoglobin.
3. Removes excess glucose from the bloodstream to store as glycogen.
4. Removes potential poisons from the blood.

Front 31

bile ducts

Back 31

passageways that carry bile

Front 32

hepatic duct

Back 32

carries bile from the liver

Front 33

cystic duct

Back 33

carried bile from the gallbladder

Front 34

common bile duct

Back 34

carries bile to the duodenum

Front 35

gallbladder

Back 35

pear-shaped sac under the liver that stores and concentrates bile. Empties through the cystic duct into common bile duct leading to duodenum.

Front 36

pancreas

Back 36

feather-shaped organ located behind the stomach that works with both the digestive and endocrine systems. Produces pancreatic juices which aid in digestion and secretes insulin for carbohydrate metabolism.

Front 37

peritoneum

Back 37

lining of the abdominal and pelvic cavities

Front 38

appendix

Back 38

small pouch attached to the cecum with no known digestive function
