Step-by-step solution
Anal cerci: A pair of anal cerci arises from the lateral sides of the 10 th segment in both males and females. It has a sensitivity to sound & vibrations. Gizzard/Proventriculus: It consists of six chitinous teeth and helps in the grinding of food materials. The outer membrane is thick to help in grinding. At the junction between gizzard and midgut, 6 - 8 finger-like tubular structures are present called hepatic caeca. These hepatic caeca help in the secretion of gastric juice and absorption. Spiracles: The respira
