they will chew the food again

At rest, they will chew food again, the process is like this after eating, all food enters and is accommodated into the large stomach (rumen), here there are many food-destroying bacteria, then the food that has been digested in the large stomach will be sent to the reticulum here to be processed into small balls or called a bolus.

Then it is sent back to the mouth to be chewed again, After being chewed until smooth, the bolus will be sent to the omasum, to be digested again until it is really smooth, then the food is sent to the abomasum to absorb the nutrients. And after the nutrients are absorbed... the rest comes out as 'e'e...
Incredible creation of the Almighty Creator...
Luckily, human digestion isn't like that...
