Animal Nutrition I (Ch. 41)
Keywords • • Heterotroph Autotroph Herbivore Carnivore Omnivore Intracellular digestion Food vacuole Extracellular digestion • Gastrovascular cavity • Alimentary canal • Basic parts of alimentary canal • Roles of mouth and stomach in digestion
Some of the best known and fascinating adaptations of animals involve their feeding and digestion
Examples: • Reptile swallowing prey • Baleen whales
Python
Starfish
Chiasmodon niger
Cryptopsaras couesi
Eurypharynx pelecanoides
Categories • I. Autotroph • II. Heterotroph – A. Herbivore – B. Carnivore – C. Omnivore
Today we’ll focus on heterotrophs: Digestion • Basic principles • Invertebrates • Humans
Why is digestion necessary? • Macromolecules cannot easily enter cell COO- NH 3+ cytoplasm peptide Cell membrane
Small molecules such as amino acids can cytoplasm Peptide being digested Cell membrane

Intracellular digestion vs. Extracellular digestion
Extracellular digestion • A. outside organism • B. gastrovascular cavities • C. alimentary canal
Extracellular digestion • A. outside organism • B. gastrovascular cavities • C. alimentary canal
Gastrovascular cavity: Hydra
Extracellular digestion • A. outside organism • B. gastrovascular cavities • C. alimentary canal
Gastrovascular cavity vs. Alimentary Canal
Alimentary canal: a simple view
Basic parts of alimentary canal Mechanical digestion mouth storage absorption anus
Alimentary canal: mammalian
Mouth • Mechanical • enzymatic
Stomach
Digestive mechanisms in stomach • Mechanical • Chemical • enzymatic
