*The descending colon has '''two''' taenia.
*The descending colon has '''two''' taenia.
**Between the two taenia are distinct sacculations that house the faecal balls.

==Microbial Environment==
*Microbes convert carbohydrates to volatile fatty acids (VFAs).
*The microbial population exists in the caecum and ventral colon.
*It is mixed; there are both bacteria and protozoa.
*Microbes are anaerobic.
*The microbial population is dependant on diet and frequency of feeding, as different microbes are suited to digesting different things.
**The number of microbes can change 100 fold in a 24 hour period.
*Environmental factors of the caecum and ventral colon can influence fermentation of microbial population.
**Environmental factors include:
***Frequent intake of food
***Constant temperature
***Constant mixing
***Removal of the products of fermentation by absorption and peristalsis
***Stable osmotic environment i.e. normal intake of water
*VFA's produced include:
**Acetate
**Propionate
**Butyrate
*Factors that promote VFA production:
**An optimum pH of 6.5
**Anaerobic environment
**Gut motility.
