Digestion in unicellular organisms
|
-amoeba: phagocytosis

Cnidarian Digestion
|
tentacles bring food, break food, for intracellular digestion and undigested food is expelled through mouth
|
|

Annelid Digestion
|
earthworms have one way digestion
-crop:store food -gizzard:grind food -intestine:for digestion and absorption |
|
|
Arthropod Digestion
|
insects similar to earthworms
-jaws:chewing -salivary glands: improve digestion |

Human Digestion
|
oral cavity -> pharynx -> esophagus ->stomach ->small intestine through pyloric spincter->large intestine -> anus
