Define the 8 possible pathways for nutrients in the body.



Ingestion: To eat, typically orally

Digestion: Chemical breakdown of nutrients requiring enzymes to get smaller pieces (small enough to be absorbed)

Absorption: Passing of nutrients through small intestinal wall into the inside of the body (into one of two transportation systems)

Transportation: Act of carrying nutrients in the vascular or lymphatic system First four pathways generally occur in order

Metabolism: process where nutrients are broken down to yield energy (work, heat) or rearranged into body structure
End products of metabolism = Energy (ATP) + H2O + CO2(carbon dioxide)

Interaction- One/Many nutrients working with other nutrients

Storage: Keeping nutrients for later use

Excretion: Eliminating nutrients, majority through urine and feces
