Within the buccal cavity, the food comes in contact with saliva and passes through the oesophagus into the crop. The oesophagus opens into a sac-like - crop, which is used for storing food. Such similarity in structures indicates that probably peritrophic mem­branes from mid gut mix up with saliva at the time of regurgitation. From each reservoir a salivary duct runs anteriorly. Fix the specimen in a dorsal position on a dissecting tray with the help of pins passing through abdominal sterna and coxa of legs. Pharynx: It is a anterior most narrow part in the head region between mouth and oesophagus. Digestive system in cockroach: Cockroach is an omnivorous. Food is captured by the bilobed tongue. In the inner wall, the epithelial cells throw fine filaments within the lumen of mid gut. the mouth opens into a short tubular pharynx, leading to a narrow tubular passage, the esophagus.

OMNIVOROUS, i.e. Cockroaches have a complicated digestive system which allows them to absorb nutrients, digest their food, and stock up fatty bodies just the same way humans store fat (Orkin, n.d.). Salivary glands, he­patic caeca and glands in the lining epithe­lium of the gut are digestive glands. It is a natural instinct that men loves the place where he gets birth and where he is brou... Patriotism Patriotism means love and regard for the country. the mouth opens into a short tubular pharynx, leading to a narrow tubular passage, the esophagus. The crop is followed by a gizzard or proventriculus. The Alimentary canal has been divided into three main parts: Foregut Digestive System of Cockroach: The cockroach has well developed digestive system comprising the alimentary canal and associated digestive glands. The food is then subjected to a variety of biochemical reaction within a specialized digestive system. It has mouth for ingestion and anus or cloacaI aperture for egestion. Mouth is for ingestion and anus is for egestion.• It can be divided in to 3 parts.• 1/foregut• 2/ mid gut• 3/hind gut 3. The alimentary canal of cockroach is divided into foregut, midgut, and hindgut. The digestive system consists of an alimentary canal and digestive glands. straight slightly coiled dig tube, open at both ends, complete dig. Answer. Digestive System of Cockroach. Foregut / Stomodaeum: It is the part of alimentary canal anterior to the gastric cecae and comprises of-i. Alimentary Canal: ADVERTISEMENTS: The alimentary canal consists of three parts namely: (i) Foregut: Foregut or the stomodaeum is the first part of the alimentary canal. •At the junction of gizzard and mesentron there are 6-7 small finger like projection known as hepathic caeca. 2.41). The internal lining of the mid gut and the hepatic caeca also produce digestive juices. It can eat any kind of organic matter. Thus its mouth parts are modified accordingly for chewing the food.
