Unit 5: Rock Your Body!Flip Flopdue WEDNESDAY!

ObjectivesWe are learning about…

the digestive systemWe 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

Agenda

•Catalyst 5

•Organ Puzzle &

iNotes 30

•Digestion Intro 15

bovine digestion

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

Digestive System

Puzzle & iNotes1.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!

26minutes!

1

Puzzle & iNotes1.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?

26minutes!

Mechanical vs.

Chemical

mechanical

digestion is the

process of physically

breaking food down

into smaller pieces

chemical digestion

is the process of

changing food on a

molecular level due to

enzymes & microbes

•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 mouth…

•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 esophagus…

epiglottis

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 stomach…

2 to 4 hours

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…

Pathway small intestine…

• Digested food moves through the rest of the small intestine and passes over 1000’s of villi

• Villi are tiny, finger-like projections that help ABSORB digested food = connection between the digestive and circulatory systems !

BOLUS chyme

Material that can’t be digested in small intestine passes into LARGE intestine AKA colon

LARGE intestine ABSORBS water & salt from waste

Pathway LARGE intestine…

5feet

!

Any leftover waste (feces…ewww!) enters the rectum and is ELIMINATED from our body

through the anus

Pathway anus…chyme

feces

“open system”

Quick Check!1. What are the 3 main functions of the digestive system?

2. Describe the size of a macromolecule.

3. Explain the difference between mechanical & chemical

digestion.

4. Where does peristalsis occur?

5. What happens in peristalsis?

6. What is the role of an enzyme?

7. Describe how the digestive system works as an open

system.
