Which region of the ruminant stomach can trap heavy objects?
A
rumen
B
reticulum
C
omasum
D
abomasum
Explanation: 

Detailed explanation-1: -Reticulum. Frequently called the ‘honeycomb, ‘ this part of the stomach is attached to the rumen with thin tissue. Its function is to trap heavy or particularly dense objects such as rocks or metal, or particles of food too large to digest.

Detailed explanation-2: -The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

Detailed explanation-3: -Ingesta flow freely between the reticulum and rumen. The main function of the reticulum is to collect smaller digesta particles and move them into the omasum, while the larger particles remain in the rumen for further digestion. The reticulum also traps and collects heavy/dense objects the animal consumes.
