Question

In Earthworm, gizzard occurs in segment

• A. 5
• B. 6
• C. 8
• D. 10

Answer 1

The correct option is C 8

In earthworm, a terminal mouth opens into a buccal cavity which leads into a muscular pharynx. A small narrow tube, oesophagus continues into a muscular gizzard (8-9 segments). It has a thick wall of circular muscles lined by columnar cells which is further lined by the cuticle. The gizzard grinds the food into a fine state. It helps in grinding the soil particles and decaying leaves. The gizzard uses stones that the earthworm eats to grind the food completely.

So the correct answer is '8'.
