SYSTEM SYNERGY
The Interaction between Fuel, Flow, and Filter
The Three-System Loop
Extracts
Digestive takes nutrients from food.
Transports
Circulatory delivers those nutrients to cells.
Filters
Urinary removes the waste from the blood.
The Vitamin Case
"Marc eats a balanced diet but his cells aren't getting fuel."
Diagnosis:
Interaction Failure. The digestive system is doing its job, but the absorption (interaction) is failing.
Interaction is Key
HOMEOSTASIS
"Maintaining Balance"
No system functions alone. They are all interdependent to benefit the entire organism.

DIGESTION MASTER
Think about it: Every cell in your body is currently being "fueled" by what you ate for breakfast, and "cleaned" by your kidneys right now.
What's one question you still have about how your body processes food or waste?
Fuel and Filter Slides Unit 8B
Fuel & Filter
Systems
Processing Nutrients and Eliminating Waste
Breaking Food Down
Mechanical
Physical breaking into smaller pieces.
Example: Teeth chewing, Stomach churning.
Chemical
Enzymes/Acids breaking bonds into molecules.
Example: Saliva (Amylase), Stomach Acid.
The Digestive Route
Stomach
Churns food into CHYME
Small Intestine
ABSORBS nutrients into blood
Large Intestine
Reabsorbs WATER & prepares waste
The Villi
Secret
Finger-like projections that line the small intestine.
Why they matter:
They create massive surface area to soak up every possible nutrient.
Surface Area
More space = More absorption = More energy
The Urinary Filter
THE KIDNEY
Filters waste materials from the blood to maintain homeostasis.
THE BLADDER
Stores liquid waste (urine) until the body is ready to release it.
