Notes: Overview of Digestive System
               (pg 2)
• Includes digestive tract and accessory organs
• Functions: break down food, absorb nutrients,
  eliminate waste
Digestive Tract
• Also called the alimentary canal or
  gastrointestinal (GI) tract
Digestive Tract
• Also called the alimentary canal or
  gastrointestinal (GI) tract
• Long continuous tube (9 meters) that extends
  from mouth to anus
Digestive Tract
• Also called the alimentary canal or
  gastrointestinal (GI) tract
• Long continuous tube (9 meters) that extends
  from mouth to anus
• Includes mouth, pharynx, esophagus,
  stomach, small intestine and large intestine
Accessory structures
• Tongue and teeth
• Function: mastication (chewing)
Accessory Organs
• Salivary glands, liver, gallbladder, and pancreas
Accessory Organs
• Salivary glands, liver, gallbladder, and pancreas
• Function: secrete fluids into digestive tract
Digestive System Activities
1. Ingestion: Taking in food
Digestive System Activities
1. Ingestion: Taking in food
2. Mechanical digestion: large pieces of food
   are broken into smaller pieces through
   chewing and stomach churning
Digestive System Activities
1. Ingestion: Taking in food
2. Mechanical digestion: large pieces of food
   are broken into smaller pieces through
   chewing and stomach churning
3. Chemical digestion: Complex molecules of
   carbohydrates, proteins, and fats are
   transformed into smaller molecules that can
   be absorbed. Hydrolysis uses water to
   chemically break molecules apart. Digestive
   enzymes speed up the process of hydrolysis
Digestive System Activities
4. Movements: First movement is swallowing
  (deglutition). Then mixing movements in the
  stomach. Peristalsis = rhythmic contractions
  that move food particles through the digestive
  tract.

5. Absorption: Simple molecules pass through
  cells lining the small intestine and enter the
  blood or lymph capillaries

   digested are eliminated through defecation
