The Must-Knows of Digestion

13

Solids, Liquids,

and Wastes!

Oh my!

Slide image

14

Solids vs. Liquids? NO!

Solids AND Liquids!

  • Both solids and liquids are ingested

  • Both solids and liquids have them same path and experiences

  • Both solids and liquids are broken down from polymers into monomers by enzymes

  • Both solids and liquid monomers are absorbed (if they can be) to be used in metabolism

  • Both solids and liquids leave behind wastes containing undigested, unabsorbed materials in the DT

  • Both solids and liquid wastes in the DT exit as feces!
