Tell the services each system gets from the others

4. Multi Level Thinking responses
Multi level responses are responses that take an explanation to its furthest logical point.
Example:
How will exercising regularly affect your heart rate?
Initially your heart rate increases during exercise
Over time exercise makes your heart both bigger & stronger, pumping more blood with each beat
(The exercise also stimulates production of new blood vessels.)
As a result, the heart will be more efficient and the heart rate will decrease both during exercise and after exercise
3 different
levels of
response

7. What do the Digestive, Respiratory & Circulatory systems do?
Digestive system
What this system does:
Breaks down food
Releases nutrients
(sugars, fats, protein, vitamins &water)
to body so all cells get energy & other nutrients to function properly
Removes some wastes & toxins
Respiratory System
What this system does:
Provides O2 for digestive system cells
Gives off CO2 that is transferred by the circulatory system from all body cells
Circulatory System
What this system does:
Transports O2 to & CO2 from cells (Respiration)
Delivers nutrients to cells (Nutrition)
Takes wastes & toxins from cells for disposal
Key part of immune system
