how the lining of mud gut in cockroach is protected from hard particles
Answers
In effect, the inside of the stomodeum is continuous with the outside of the insect's body. Since exoskeleton is secreted to protect the insect externally, it is not surprising to find that cells lining the foregut produce a similar structure (known as the intima) to protect themselves from abrasion by food particles
Answer: The inside of the stomodeum is continuous with the outside of the insect's body. Since the exoskeleton is secreted to protect insects from the outside, it is surprising that the cells that line the foregut produce a similar structure (known as the intima) that protects them from wear by food particles.
Explanation:
Mesenteron, which includes the entire stomach / ventricle. There are 6 pairs of stomach (stomach-related) caecae in the gizzard and stomach joints. At the anterior end of the stomach, it is arranged like a ring-shaped pocket. The anterior lobe of each group of gizzards extends beyond the proventriculus and the posterior lobe extends to the proventriculus. Digestive fluid flows into the stomach through caecae secretions. The midgut is lined by the peritrophic membrane, not the cuticle. The same membrane protects the stomach wall from damage while allowing complete permeation of enzymes and digested foods.
