Document Summary

Different species, different needs, different systems, but common themes. 4 different digestive systems: simple system (w/o caecum, simple system (w/ functional caecum, ruminant system, avian system. No matter what digestive system they have, they still digest (common theme) Different systems to understand how different organisms break down foods.

Digestive system refers to the gi tract & associated organs (liver, pancreas, gallbladder) General terminology for dietary carbohydrates (cho) & digestion. Digestibility does the host organism have the enzymes necessary to digest cho: digestible cho versus non-digestible cho (fibre). (non-digestible meaning we do not have enzymes to ferment) Solubility is cho soluble in the aqueous environment of the digestive tract: yes = soluble; no = insoluble.
