This is NOT all inclusive study guide. It is the more difficult topics that you may encounter in the chapters
for the exam. You are responsible for all information from Chapter 24 through Chapter 26.
Component Function (Use Ingestion, mechanical processing, secretion, Hormones or Digestive
of GI Tract absorption, digestion, and excretion WITH a specific function) Enzymes Released
Oral Cavity is done as an example with what kind of knowledge you should (indicate the cell if
know! applicable)
1. Mechanical Processing due to teeth, tongue and chewing Salivary Amylase:
(mastication) Salivary glands Lipids:
2. Ingestion due to food intake in mouth tongue
ORAL 3. Secretion due to salivary amylase and saliva via salivary glands or
CAVITY lingual lipase secretion via tongue
4. Digestion of carbohydrates by salivary amylase; Digestion of
Lipids by lingual lipase; NO protein digestion
Transport of materials to the stomach Does not produce enzymes
Swallowing (Delglutination)
ESOPHAGUS
Chemical breakdown of materials by acid and enzymes.: Amylase, Lipase, Pepsin ,
mechanical processing through muscular contractions HCL
1.Storage of ingested food (intrinsic factor and HCL
2. Mechanical breakdown of ingested food (amylase, lipase) activate pepsin)
3. Disruption of chemical bonds in food material by acid and Gastrin-Acid production by
enzymes paritetal cells &
4. Production of intrinsic factor, a glycoprotein required for stimulation of gastric
absorption of vitamin B12 in small intestine motility; mixing waves
STOMACH Secretion of intrinsic factor & HCLd, pepsinogen to pepsin increase in intensity
Digestion- carbohydrates lingual lipase, proteins, Somatostatin – inhibit the
reselase of gastrin
Ghrelin – appetite
(antagonistic to leptin –
induces satiety.)
Obestatin – decrease
appetite and inhibit
thirst.
Enzymatic digestion and absorption of water, organic GIP
substrates, vitamins, and ions Secretin-
Pancreatic alpha-amylase –
breaks down remaining
complex carbohydrates
DUODENUM CCK-bile secretion and
ejection of bile from
gallbladder
VIP-dilation of intestinal
capillaries
Enzymatic digestion and absorption of water, organic Does not produce enzymes
substrates, vitamins, and ions
