the alimentary canal of the cockroach is divided into 3 parts i.e. foregut, midgut and hindgut.the mouth opens to a small tubular pharynx leading to a narrow tubular passage called oesophagus. this opens to a sac like structure called crop which helps in storing food.the crop is followed by gizzard which helps in the function of grinding the food.a ring of 6-8 blind tubules called hepatic or gastric caecea which is present in the junction of foregut and midgut, which secretes digestive juice. at the junction of midgut and hindgut there are several thread like structures called malphigian tubules which helps in the removal of excretory product from haemolymph. the hind gut is differentiated into ileum, colon and rectum. the rectum at last opens out through anus.
Digestive system of cockroach is very easy. Roach mouth opens to esophogus, where saliva mix with food (oft excrement or other food waste / rot.] Then this mix saliva and food is pushed to crop of insect, but not digest it there. Next, from crop the food moves to gizzard which crush / process food before leading to stomach. After stomach, this reaches intestines; to do actual digestion making component molecules which roach's body may use.
These molecules pass direct to blood through intestine wall; then carried to rest of roach's body with circulatory system. Energy from these process be stored in fat bodies throughout roach.
Excess / non usable part of food (or bi-product of digestion) are passed to rear intestine, and then colon section to form "pellet" which then roach will excrete to remove through its anus.
I hope this helps, I cannot see a way to attach diagrams into answer itself so here is link to a good picture: http://www.entomology.umn.edu/cues/4015/morpology/de.jpg
Hope this will help you!
The crop on a cockroach holds food, the gastric cacea has enzymes that help digest food, and the gizzard grinds food before it goes to the stomach. The midgut absorbs nutrients, the ileum absorbs fats, and the colon eliminates waste.
The digestive system of a male cockroach includes a stomach for breaking down food. It also contains a small and large intestine.
they secrete gastric juices that will pour of flow into the stomach to aid in digestion
In mosquitoes, the gastric caeca are responsible for ion and water transport. In the cockroach, the gastric caeca contain bacteria which aid in digestion. Leeches store concentrated blood in their gastric caeca. In grasshopper, chemicals are secreted from the gastric caeca in the stomach and from the salivary glands. So the general role of the gastric caeca is for digestion, but without knowing the species, your question is a little difficult to answer.
Also known as digestive caeca or hepatic caeca. Pyloric caeca (outpocketing) extends from the pyloric stomach of the starfish into each of the five arms.
The function of the pyloric caecum is to aid in digestion. It is also known as the hepatic caeca and digestive caeca.
Pyloric caeca or hepatic caeca helps in a starfish's digestion. It is located in the their arms. After swallowing their prey, they then place it in their Pyloric caeca where the digestion process starts.

THE GASTRIC CAECA ARE SMALL SAC-LIKE APPENDAGES THAT NORMALLY CONTAIN GASTRIC JUICES THAT ARE INVOLVED IN THE DIGESTION OF FOOD IN THE MID GUT.

food --> mouth --> esophagus --> crop (dilated when feeding; flocculated salivary glands present around crop) --> gizzard (chitinous teeth; grind food)--> midgut (includes digestive, or gastric, caeca)--> Malphigian tubules--> hindgut (still has ileum, colon and rectum)--> anus-uc berkeley
Caeca et Obdurata was created in 1593.
