Step-by-step solution
In a cockroach, Hepatic caeca (or gastric caeca) are a ring of 6-8 blind tubules present at the junction of the foregut and midgut, which secrete digestive juice. Malpighian tubules are a ring of 100-150 yellow-coloured thin filamentous tubules present at the junction of the midgut and hindgut, which help in the removal of excretory products (uric acid). Gizzard (proventriculus) has an outer layer of thick circular muscles and thick inner cuticle forming six highly chitinous plates called teeth, which help in grind
