Question

Give the location of hepatic caeca in cockroach? What is their function?

Answer 1

Hepatic caecum or hepatic cecum is a name used in describing various physiological structures in some crustaceans, insects and cephalochordates. "Hepatic" refers to the liver, and the hepatic caecum may perform some functions that are analogous to the functions of the liver in vertebrates.

In cockroach, the hepatic caeca is present at the junction of the foregut and midgut. It is a ring of 6-8 blind tubules. Their function is to secrete digestive juices to facilitate digestion.
