Step-by-step solution
In the alimentary canal of a cockroach: Crop is a sac-like structure used for storing of food. Gizzard (proventriculus) has an outer layer of thick circular muscles and thick inner cuticle forming six highly chitinous plates called teeth, which help in the grinding of food particles. Hepatic or gastric caeca is 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 structures present at t
