Which structure is secondarily involved in hardware disease when heavy objects settle there?

• A. Reticulum
• B. Rumen
• C. Omasum
• D. Abomasum

Answer: (A)

In hardware disease the problem starts with heavy objects settling in the reticulum. The reticulum is the cranial part of the forestomach and lies right against the heart and diaphragm. Its honeycomb lining tends to trap dense metal objects that are swallowed, so these objects tend to accumulate there rather than in the other chambers. If a sharp object penetrates the reticular wall, it can reach the pericardial sac and cause traumatic pericarditis—a secondary consequence of the initial impaction in the reticulum. The other compartments (rumen, omasum, abomasum) are farther back and are less likely to harbor these heavy items or cause this cardiac irritation, making the reticulum the correct structure involved.
