Physical digestion takes place in the ventriculus. Chemical digestion takes d. Physical digestion takes place in the proventricultus. Chemical digestion takes place in the gastric caeca. takes place in the proventriculus. place in the proventriculus. takes place in the ventriculus 2 19g On the following pages:Explanation / Answer
3. The gastric caeca is involved in digestion and nutrient absorption. These are finger like projections, originating from the midgut. They provide extra surface area for nutrient absorption and enzyme secretion. Nutrients such as carbohydrates, proteins and fats are absorbed in the gastric caeca. Malphighian tubules are important part of excretory system and help in absorption of waste products. The crop is the out pocket of the esophagus, and stores swallowed food and water until it can be passed. The proventriculus is the glandular stomach where digestion occurs.
Option c.
9. The wings are outgrowth of body wall in the grasshopper that help it fly. They are attached to the thorax. The metathorax and the mesothorax bear wings. The mesothoracic wings are attached to the mesothorax and are used to protect the metathoracic wings that are attached to metathorax.
Options: b, d, e
10. Physical digestion is breakdown of food by physical action. Chemical digestion is the breakdown of carbohydrates, fats and proteins by digestive enzymes. Physical digestion of food occurs in the ventriculus, where digestive enzymes are mixed with the food. The muscular part of stomach uses small, hard pebbles or sand to grind the food into more smaller digestible particles. The proventriculuc, present before the ventriculus, produces digestive enzymes and hydrochloric acid that initiates the chemical digestion of food. Gastric caeca is required for absorption of nutrients.
