Question

In Cockroach, gizzard is part of

• A. Respiratory system
• B. Digestive system
• C. Immune System
• D. Circulatory system

Answer 1

The correct option is B Digestive system

The digestive system of cockroach consists of the pharynx, the esophagus, the crop, the intestine, and the gizzard. After the food passes through the esophagus, the food moves into the crop where it is stored and then eventually moves into the gizzard. The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process.

So the correct answer is 'Digestive system'.
