what is the function of alimentary canle in case of cockroach

Dear student, The alimentary canal is divided into: 1. Foregut 2. Midgut 3. Hindgut 1. Foregut: a. Is lined by a cuticle. b. Consists of a mouth which opens into the tubular pharynx, leading into the oesophagus, which further opens into a sac-like crop that stores the food. C. The crop leads to a gizzard (proventriculus). The gizzard helps in grinding food as it has an inner layer with six chitinous teeth. d. The junction of the foregut and midgut has rings of 6 to 8 blind tubules called hepatic or gastric caecae, which secrete digestive juices. 3. The hindgut is broader than the midgut, and consists of: a. Ileum b. Colon c. Rectum (opens out through the anus). Regards
