Answer 2

$\text{\underline{\underline{Stomach\:of\:Ruminant\:Animal:}}}$


The stomach of ruminants is known as compound stomach. It has 4 well defined chambers or compartments.

=> $\sf{\underline {Rumen}}$

=> $\sf{\underline {Reticulum}}$

=> $\sf{\underline {Omasum}}$

=> $\sf{\underline {Abomasum}}$


⚫Rumen is the first and the largest chamber mainly meant for the storage of food.

⚫In camel and deer, omasum is absent and water cells project from Rumen.

⚫Digestion of cellulose takes place by fermentation, with the help of symbiont bacteria and protozoans.

⚫Abomasum is the true stomach, which secretes gastric juices.

⚫Rumen and reticulum harbour large populations of anaerobic cellulolytic bacteria like Rumenococcus which secretes the cellulase enzyme for the fermentation of cellulose.


$\text{\underline{\underline{NOTE:}}}$

⚫Cellulose is simplified into small chain fatty acids.
