| 1. | Genotoxicity of nonfibrous and fibrous particles is characterized by high production of ROS from inflammatory cells.
|
| 2. | Peristaltic muscle contractions ( waves of motion ) help to separate fibrous and non-fibrous particles.
|
| 3. | Symbiotic bacteria in the cecum help to further digest the non-fibrous particles into a more metabolically manageable substance.
|
| 4. | The non-fibrous particles are then moved backwards up the colon, through the illeo-cecal valve, and into the cecum.
