So, in grasshopper (or cockroach) the different processes of nutrition takes place in fully developed digestive system. This is where the reproductive and digestive systems are. These organs are usually situated at the oesphageal end of the stomach and are very variable in number. The grasshopper feeds on green vegetables while the cockroach feeds on household materials like books, sugar and food. 4. Grasshopper Anatomy Like all insects, the grasshoppers have three main body parts – the head, the thorax and the abdomen. A cellular organelle in protozoans that performs a function similar to that of the small intestine in humans is the: food vacuole: Based on their pattern of nutrition, most animals are classified as: heterotrophic: The grinding action of food which occurs in the gizzard of a grasshopper is an example of which nutritional process? The midgut (called the Mesenteron in some books) runs from the ‘gastric caeca’, a series of stubby pointed tubes leading off from the stomach, to just before the Malpighian tubules, a series of long thin tubes. International Transport & Shipping Co. The bird’s stomach can be seen to be easily divided into two sections, the proventriculus and the gizzard. A red-coloured small spleen remains morphologically attached to the outer side of proventriculus.

The digestive enzymes help to break down the food and allow the nutrients to be absorbed through the lining of the stomach and transported to various parts of the body. It too, is lined with mucosa. Grasshoppers have the potential to be utilized in bioreactors, which could improve straw utilization efficiency in the future. Enzymes from the liver and pancreas help digestion. Frons: The front part of the head between the compound eyes and … From the mouth the food passes through the esophagus into the crop. They are the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, … Spiracles: Breathing pores.
