 Hinges allow it to open  Sack-like shape with
to receive things & close space inside to hold stuff
to crush them
 Drawstring opening can
 Metal provides hard
open to receive things,

from slipping out
Similar digestive organ:
Similar digestive organ: Stomach
Mouth
Function:
Dry things by
absorbing water
Relate structure to
function:
 Cotton material is very
absorbent
 Tiny strings on surface
provide more space for
absorbing stuff
Similar digestive organ:
Small intestine
MOUTH
ESOPHAGUS
Structure:
Hinged jaws, hard teeth, muscular
tongue
Mechanical Digestion/Absorption:
Crushing, grinding, moistening food
Chemical Digestion:
Starch salivary amylase Glucose
Structure-Function Connection:
Jaws open & close to crush; hard teeth
grind; tongue mixes food w/ saliva
Structure:
Long muscular tube
Mechanical Digestion/Absorption:
Pushes food from mouth to stomach by
peristalsis (waves of muscle contraction)
Chemical Digestion:
None
Structure-Function Connection:
Muscles help squeeze food down the
tube
LIVER
Major Function:
Makes bile for lipid digestion in
small intestine
GALLBLADDER
Major Function:
Stores and releases bile into
small intestine
PANCREAS
Major Function:
Makes enzymes for small intestine
STOMACH
Structure:
Muscular sac containing acids & enzymes
Mechanical Digestion/Absorption:
Food churned/mixed with acids &
enzymes; acids kill bacteria & loosen
food particles
Chemical Digestion:
Protein pepsin
Peptides
Structure-Function Connection:
Muscles in stomach walls contract to
churn food

Title: Digestion Project Work Time


Homework:
 Complete up to step 3 on the digestion project by Monday!
Do Now:
 Which
organ is the most confusing to you right now? Why? If
this isn’t addressed by the end of class, ask the question!

Today’s Objectives:

Follow carbohydrates, proteins, and lipids through the digestive system.

Decide on the creative form your project will take, and begin writing.
SMALL INTESTINE
Structure:
Structure:
Long narrow tube with millions of
folds (villi) and hairs (microvilli)
Chemical Digestion:
Starch
amylase
Disaccharides
Glucose
Monosaccharides
Protein
trypsin
Peptides
Peptides
peptidase
Amino acids
Lipids
LARGE INTESTINE
lipase
Fatty acids &
glycerol
Mechanical Digestion/Absorption:
Bile breaks up lipid globs
Villi absorb all nutrients/monomers
into the bloodstream (glucose,
amino acids, fatty acids…)
Structure-Function Connection:
Long tube + villi/microvilli provide a
lot of surface to absorb all the
nutrients.
Wide tube w/ many bacteria living
there
Chemical Digestion:
Bacteria break down wastes and
release vitamins
Mechanical Digestion/Absorption:
Water and vitamins absorbed into
bloodstream
Waste is solidified and compacted
Structure-Function Connection:
Width of tube provides space for
waste to build up and get compacted
RECTUM
Major Function:
Store digestive waste (feces)
ANUS
Major Function:
Release feces from the body

The Creative Portrayal of the Digestive System
The Project: Follow the journey of some food through the digestive system from the
perspective of the food.

Choose a food that contains the following organic compounds: carbohydrates,
protein, and lipids.

Trace the path of that food as all of its components are digested.
You will portray this journey in ONE of TWO ways (you choose ONE):

Creative Writing: Write a creative story from the perspective of the food. Describe
your journey through the digestive system.

Illustrated Storybook: Combine the above option with some illustrations to trace the
path of the food through the digestive system. You might want to describe each
major component of the digestive system on a different page (Hint: a great way to
do this would be to create the story in PowerPoint, so that each slide is a page).
Your project should illustrate the following big ideas:

The relationship between structure and function in the human digestive system

The process of breaking down food into small, building block molecules

The importance of enzymes in metabolism

Digestion Project Overview
Begin Digestion Project
 Complete

Be specific when identifying the sources of carbon compounds in your
meal.
 Complete

Step 1
up to Step 3 for the start of Monday’s class.
Pay close attention to how the carbon compounds are broken down from
the complex polymers to the simplest monomers that are absorbed into
the blood stream. How many stages does it take for each to do this?
Objectives for Class:
 Describe the structures and functions of digestive system organs, and explain how they relate to each other
 Explain the purpose of the Digestion Project and identify what meal you will use.
