Document Summary
Digestion: the physical, chemical and enzymatic means the body uses to render a feedstuff ready for absorption: physical: mastication and peristalsis, chemical: hydrochloric acid and bile, enzymatic: hydrolytic enzymes. All animals have similar metabolic pathways bit they use them differently and digest differently. These differences allow different species to coexist in the environment, but in different places along the food chain. Mono gastric: (simple stomach)- one stomach: dog, cat, human, horse. Ruminant: (complex stomach)- multiple stomach compartments: cows, goat, sheep, llama, alpacas. Involuntary re ex bolus(a rounded mass of food ready to be swallowed) Peristalsis the squeezing movement produced by muscles while swallowing: nutrient breakdown: rumination(fermentation, regurgitation, eructation) . Glandular stomach: a stomach with glands that have more enzymatic and chemical breakdown, churning of food, storage) Rumination: the process in ruminants where a bolus of rumen contents is regurgitated, remasticated, and reswallowed for further digestion. Fermentation: the chemical breakdown of substances via microorganisms.
