Secretin- a hormone that stimulates basic pancreatic juicesGastrin-a hormone that increases
the production of digestive juicesCholecystokinin- a hormone that
stimulates digestive pancreatic juices and bile release
Pepsin-an enzyme that digests proteins
Amylase-an enzyme that digests carbohydrates
Lipase- an enzyme that digests lipids

Outline Week One
Diagrams & layers of digestive system Tongue, palate, teeth & salivary glands Pharynx, esophagus, stomach Pancreas, liver, gallbladder & intestines
Week Two Diseases and treatments Clinical Rounds Review TEST (MARCH 1st!)

Gallbladder, Liver and Pancreas
No food goes through these Secretions ducts S.I. Food that enters the small intestine from
the stomach is called chyme (an acidic paste)

Pancreas Makes digestive juices for organic
compounds Lipase, cholecystokinin & nuclease Secretin stimulates basic solution to
reduce pH of chyme

Liver Versatile organ! Tiny units called hepatic lobules Secretes bile
hepatic duct Lipid digestion
Other roles: creates phospholipids, cholesterol, filters blood, turns carbs to fats, makes parts of blood, stores iron/vitamins, filters toxins

Gallbladder Overflow storage site for bile Release of bile controlled by
cholecystokinin

THE INTESTINES
![Page 9: Secretin - a hormone that stimulates basic pancreatic juices](https://reader035.vdocuments.site/reader035/viewer/2022062310/568166de550346895ddb0bdb/html5/thumbnails/9.jpg)
Peristalsis Rhythmic movement of muscles that
moves food through the large and small intestines

Small Intestine Chyme here Three parts
Duodenum Ilium Jejunum
Coated with villi to increase SA

Small Intestine’s Role Finish digestion Absorb nutrients Move food remains to large intestines Secrete watery fluid to help absorb
digested nutrients Note: If food is rushed through small
intestines, there will be low nutrient absorption, increased defecations & diarrhea

Large Intestine Absorb water & electrolytes Three parts
Cecum Colon Rectum

Magic School Bus! Name as many components of their trip
that you recognize as part of the digestive unit These can be facts you thought of, names
or functions of structures, etc.

Activity Trace the path of a piece of food through
the digestive system. List the sites that you see (in order) and what is occurring there.
