Objectives
 We are learning about…
 the
Agenda
digestive system
 We will be successful when we can…
 explain how the
digestive system
converts macromolecules from food into smaller
molecules that can be used by cells for energy
and for repair and growth

Digestion Intro 15
Digestive System
1. converts macromolecules from food into
smaller molecules that can be used by cells for
energy and for repair and growth
2. absorbs nutrients into
the blood stream
(circulatory system!)
3. eliminates waste
Puzzle & iNotes
1.Cut out digestive organs & labels
2.Organize digestive organs & labels in order
(p 915)
3.Glue digestive organs & labels in your notes
4.Color primary organs green & accessory organs
yellow
5.Illustrate your notes by answering the iNotes
questions!

Puzzle & iNotes
1. Digestion starts in the mouth. What 2 digestive processes occur there?
2. What is the main function of the stomach? How does it perform this job?
3. Name the organ that connects the mouth and the stomach.
4. Why are the salivary glands, pancreas, liver, and gall bladder considered
accessory glands of the digestives system?
5. Why can we live without our gall bladder? What is its main function?
6. What is the main function of the small intestine?
7. How is the small intestine structured specifically to perform its job best? Draw a
picture clearly showing the structure of villi and microvilli.
8. By what process does food move from the small intestines to the bloodstream
so it can be circulated to the rest of the body?
9. What is the main function of the large intestine?
10.By what process does water move from the large intestines to the bloodstream
so it can be circulated to the rest of the body? Why is it important for water to be
reclaimed from the digestive system back to the body?
11.What are the functions of the bacteria that live in the large intestine?
Mechanical vs. Chemical
mechanical digestion
chemical digestion
is the process of
is the process of
physically breaking
changing food on a
food down into smaller
molecular level due to
pieces
enzymes & microbes
Pathway mouth…
• Mouth: mechanical digestion
begins as teeth chew
• Mouth: chemical digestion as
salivary glands secrete saliva
 enzyme (amylase) breaks down
starches into smaller sugars
• Mouth: food is molded into a
ball (BOLUS) by the tongue &
swallowed
Pathway esophagus…
• BOLUS passes through pharynx
& enters esophagus
 muscular tube which
connects mouth to stomach
• Peristalsis is a series of
involuntary, smooth muscle
contractions that pushes food
down the esophagus
Pathway stomach…
Stomach: chemical digestion continues
as gastric juices made of an enzyme (pepsin)
& hydrochloric acid are secreted to break
down food into smaller molecules
Stomach: mechanical digestion
continues as the muscular walls of the
stomach contract to mix food
Pathway small intestine…
Small Intestine: mechanical digestion occurs
as muscles contract to help break down food
Small Intestine: chemical digestion occurs
when the pancreas & liver secrete fluids which help
neutralize acid from the stomach plus enzymes to break
down the food even more
Pathway small intestine…
• Digested food moves
through the rest of the
small intestine and
passes over 1000’s of
villi
• Villi are tiny, fingerlike projections that
help ABSORB
digested food =
connection between
the digestive and
circulatory systems !
Pathway LARGE intestine…
Material that can’t be digested in small intestine
passes into LARGE intestine AKA colon
LARGE intestine ABSORBS water & salt from waste
Pathway anus…
Any leftover waste (feces…ewww!) enters the rectum and
is ELIMINATED from our body through the anus
“open system”
