Illeum
The last 12'of the sm.intest.-connects to lg.@ the ileocecal valve. absorbsion of food to the blood stream % lymph system is it's major function
Duodenum
shortest portion-10" of sm. intest. C-shaped curve circles the head of the pancreas-connects to jejunum. ducts from the liver,gallbladder and pancreas enter this area
Jejunum
7-8' center of sm. intest. has blood vessels, lymph and nerves in peritoneum/mesentery. These glands provide secreation for digestion-primary function and absorption
Mesentery
one or more membranes that consist of a double fold of the peritoneum invest the intestines and their appendages connecting them with the dorsal wall of the abdominal cavity
Liver

Gallbladder
3-4" lies under surface of liver. Stores and concentrates bile and releases it to sm. intest. by cystic duct
Pancreas
5" by 1" long lies behind stomach and connets to the duodenum by 2 pancreatic ducts. mostly an endorcine gland=producing digestive emzymes, secrete homrmones insulin, glucagon and somatostatin. (islet of Langerhans)
Islet of Langerhans
small slightly granular endocrine cells that form among the tubules and alveoli of the pancreas and secrete insulin and glucagon
Stomach
J shaped-empty's to the duodenum.Recieves bolus from esophagus & continues the digestive process. Contains rugae & gastic glands secrete hormone gastrin/juices=hydrochloric acid,smzymes,mucus,H2O&creates chyme.
Lg Intestine
Muscular tube 4-5'long & 2'wide. reabsorbs water, electrolytes, manufacturing vitamins form and store feces until defecation.
Cecum
receives the digestive matter from the ileum of the sm. intestine
