Digestion system of chockoch |
| Answer» The\xa0digestive system\xa0consists of the alimentary canal and\xa0digestive\xa0glands. The alimentary canal of\xa0cockroach\xa0is divided into foregut, midgut, and hindgut. The mouth opens into a short tubular pharynx, leading to a narrow tubular passage, the oesophagus.\xa0Cockroaches\xa0use\xa0their\xa0mandibles, or jaws,\xa0to\xa0bite and chew\xa0their food. From\xa0the\xa0mouth organs,\xa0the food\xa0passes into\xa0the\xa0foregut, or esophagus.\xa0The\xa0foregut opens into a crop, where undigested\xa0food\xa0is temporarily stored. The\xa0gastric sacks contain bacteria that\xa0the cockroach\xa0uses\xa0to digest its food. | |
