The Digestive System

Flashcards covering the digestive system processes, alimentary canal, digestive enzymes, pancreatic bicarbonate, and key anatomical structures.

Ingestion

Food intake.

Digestion

Food breakdown.

Absorption

Nutrients from food enter blood and/or cells.

Excretion

Food waste is released (elimination).

Energy Distribution of Food

$40\%$ of food is energy, and $60\%$ goes to heat for our bodies.
