Function 1) Break down food into nutrients 2) Absorb necessary nutrients 3) Get rid of any waste

5. Digestive System MOUTH Breaks food into smaller pieces
Saliva starts digestion

6. Digestive System
ESOPHAGUS

7. Digestive System STOMACH
Bag-like muscular organ responsible for breaking food down
Produces acid for food digestion

8. Digestive System SMALL INTESTINE Highest amount of chemical digestion
*larger than a tennis court
Highest amount of chemical digestion
Villi cells absorb nutrients

9. Digestive System LARGE INSTESTINE No digestion Absorbs water from food
Prepares undigested food for elimination

Moves air from nose to lungs

13. Respiratory System LUNGS Two spongy, air-filled organs
Inflate when breathe in and deflate when breathe out

14. Respiratory System ALVEOLI Tiny grape-like sacs located in the lungs
Responsible for gas exchange
Send oxygen to the blood
Given carbon dioxide for release

15. Cardiovascular System
Function 1)Transports materials throughout body 2) Transports nutrients and oxygen to cells

16. Cardiovascular System
HEART
Muscle located in center of chest
Size of fist
Pumps blood throughout body

17. Cardiovascular System
VEINS “Blue”
Return blood from other organs back to heart
Contain oxygen-poor blood

18. Cardiovascular System
ARTERIES “Red”
Carry blood from heart to other organs
Contain oxygen and nutrient rich blood
