Rumen
Reticulum
Omasum
Abomasum

70
Q

what is the abomasum?

A

The posterior-most portion of the ruminant stomach, sometimes referred to as the “true” stomach as it contains cardiac, fundic, and pyloric gland regions.

71
Q

What is the proventriculus?

A

The rumen, reticulum, and omasum are referred to together as the proventriculus.

72
Q

Describe the proventriculus.

A

It is essentially aglandular, consisting of tissues that allow ingesta to be further macerated by mechanical and chemical means.

73
Q

What is the reticulum?

A

A continuation of the rumen or the “2nd stomach”, is similar both in structure and function to the rumen.

74
Q

What is the principal morphological difference between the rumen and reticulum?

A

The presence of mucosal primary folds in the reticulum, reticular crests (crista reticuli).

mechanically break down the fibrous diet and is very absorptive (water and nutrients)

This is a result of the additional muscle in the mucosal layer and the tunica muscularis.
