Transcript of Digestive System

Digestive System
3) How do the respiratory and circulatory systems work together?

4) How does the nervous system work with all other systems?
Organ system that
breaks up, digests,
and absorbs nutrients from food
Functions of Digestive System
Break food
into smaller pieces
Move food
Dissolve food
with enzymes
(saliva & stomach acid)
Absorb nutrients
into the blood
Organs of the Digestive System
Breaks food
into smaller pieces
Mechanical (Physical) Digestion
Breaking food down into smaller pieces

Chemical Digestion
Changes composition
of food
Chew, mix, & churn
Saliva starts dissolving
Transports food
to the stomach
- Wave-like movement to
push food down
Mixes and Grinds
Mechanical digestion
to food
Chemical digestion
-Turns food to paste
Peristalsis moving up =
Small Intestine
-More than 20 feet long
-Continues breaking down food
with acid (
Chemical digestion
Absorbs nutrients
into the blood
Large Intestine
-Moves waste (leftovers) to be removed
Reabsorbs water
from leftovers
-Starts as liquid, comes out as...
something else
what is the function of the respiratory system?

3) bring oxygen into body
2) protect inside & keep warm
1) transport oxygen to body
Integumentary - Protect, Heat
Skeletal - Move, protect, support
Muscular - Move, protect, pump blood
Circulatory - Carry Oxygen, Heat
Respiratory - Gas exchange
Nervous - Electrical messages
Macromolecules (Large molecules)
What your body is breaking down
; Easiest to break down, 1st source of energy

Rebuild tissues/Muscles
; take longer to break down

HIGH energy
; Broken down during endurance activity (20+ minutes)
Rectum & Bladder
Storage for waste
to be removed

-Rectum holds stool

-Bladder holds urea (urine)
(Excretory System)
Organic Compounds
EQ: What are the functions of the digestive system and how does it maintain homeostasis?
Contain Carbon (C)
Digestive --> Circulatory
--> Body cells
The main elements in many organic compounds are
Carbon (C), Hydrogen (H), and Oxygen (O)
When we eat, we break down our food into organic compounds that our body can use

Notebooks Out
Body Outline
1) Finish Nervous System (brain & functions)
2) Add mouth, stomach, and intestines
3) Title "Digestive System"
4) List 4 functions
5) Explain the path of food
Notebooks and body outlines out
5) Which of the following molecules are organic?
-NaCl -CFl -NH O
-C H O -C N H O -CaCl

6) What is the difference between mechanical and chemical digestion?
