what role does the cecum play in digestion
Cecum In herbivores, the cecum stores food material where bacteria are able to break down the cellulose. This function no longer occurs in the human cecum (see appendix), so in humans it is simply a dead-end pouch forming a part of the large intestine.
Extracellular digestion Joint intracellular and extracellular digestion In hydra and other cnidarians, the food is caught by the tentacles and ingested through the mouth into the single large digestive cavity, the gastrovascular cavity. Enzymes are secreted from the cells bordering this cavity and poured on the food for extracellular digestion. Small particles of the partially digested food are engulfed into the vacuoles of the digestive cells for intracellular digestion. Any undigested and un-absorbed food is finally thrown out of the mouth.[8]
