Chemical digestion, or physical digestion?
Physical Digestion
Of the 3 types of muscle tissue in humans, what type of muscle tissue performs Peristalsis?

Smooth Muscle Tissue
The large hollow organ where food is broken down chemically and physically (p106)

(Nutrients notes)
Fat
This part of the excretory system eliminates liquid waste, called Urea, from the body (p108)
Kidney / Urinary System
Saliva has an enzyme (called Amylase) that breaks carbohydrate molecules, like in a saltine, into new substances.
Chemical digestion, or physical digestion?
Chemical
This organelle in provides storage in the cell (p.38)
Vacuole
Where water and Vitamin K are absorbed from solid waste and stored until it's time to go #2 (p.107)

(Nutrients notes)
Carbohydrate
This gas is what the lungs eliminate (p.108)
Carbon Dioxide
The gallbladder and pancreas add digestive juices that break protein and fat molecules into simpler molecules.
Chemical digestion, or physical digestion?
Chemical digestion
Of the four types of tissue in humans, this type is found mostly in your skin and linings of your organs.

Epithelial Tissue
These millions of tiny finger-like projections in the small intestine are where nutrients are absorbed into the bloodstream (p107)
