17
The pancreas secretes chemicals that aid the process of digestion. These chemicals are called

Hormones
Receptors
Antibodies
18
Why must food be broken down?
Because we only use a small amount of the food we eat
Because only some of it is usable
Because it must be small enough to diffuse into the blood
