Answer 1

Answer: (D)

Hepatic caeca

In cockroach at the junction of gizzard and mesenteron, there is 6-7 small finger-like projection known as hepatic caeca. These are hanging in the hemocoel ending blindly but opening in the midgut. Hepatic caeca produce digestive enzymes. With the help of these digestive enzymes, the digestion of food takes place in the mesenteron. After the digestion, the nutrient such as carbohydrates, fats, and proteins are absorbed by the midgut, especially in the more anterior parts including the caeca.

So the correct answer is 'Hepatic caeca'.
