Title: Nutrient Absorption
EQ: What are the interactions that occur among the systems that perform the function of nutrient absorption?

2. Today’s Standard: describe the interactions that occur among [animal] systems that perform the functions of…nutrient absorption… (B.10A)

3. Glue the reading assignment titled “Nutrient Absorption” into the left page of your notes.
If there is not space, then you may tab it and glue on your notes side and take notes underneath it.

4. Copy this diagram into your notes!
SYSTEMS INVOLVED
NUTRIENT ABSORPTION
Digestive
Respiratory
Circulatory
Copy this diagram into your notes!
*the diagram does not need to take up much space. Be efficient 

5. Reading Article Checklist:
Your highlights and map of the path food takes through the digestive system should look similar to this.
BEFORE YOU MOVE ON….Please take the time to make sure you have done this assignment correctly!

6. DIGESTIVE SYSTEM Main Parts: Mouth Esophagus Stomach Small intestine
Large intestine

7. DIGESTIVE SYSTEM Main Functions:
Mouth breaks down food into smaller pieces
Stomach acids break food into biomolecules (carbs, lipids, proteins)
Small intestine absorbs nutrients
Large intestine absorbs excess water

8. Digestive system short video. *must be in full screen mode to view.

9. Make new section in notes for next system

10. RESPIRATORY SYSTEM
Main Parts:
Nose
Mouth
Lungs
Diaphragm

11. RESPIRATORY SYSTEM Main Functions:
Nose & mouth filter air as it comes in
Diaphragm contracts and relaxes to move the lungs
Lungs expand and contract for inhaling & exhaling
Oxygen diffuses into blood

13. Make new section in notes for next system

14. CIRCULATORY SYSTEM
Main Parts:
Blood vessels
Heart
Red blood cells

15. CIRCULATORY SYSTEM Main Functions:
Heart pumps blood through blood vessels
Transports oxygen & carbon dioxide to and from the respiratory system
Transports nutrients from the digestive system to the rest of the body
Respiratory and Circulatory Systems

16. what’s in BLOOD digested food red blood cells white blood cells oxygen
waste (urea)
platelets
carbon dioxide
plasma
hormones

17. DEBRIEF:
Explain how all three systems work together for nutrient absorption in the body.
Nutrients are taken in by the digestive system through food, and the respiratory system from the air. The nutrients are moved throughout the body by the circulatory system through the blood.
