III. HINDGUT
Hindgut is ectodermal in origin and produced by the posterior invagination of ectoderm. Internal
cuticular lining is present, which is permeable to salts, ions, aminoacids and water. The main
functions of hindgut are the absorption of water, salt and other useful substances from the faeces
and urine. Hindgut is differentiated into three regions viz., ileum, colon and rectum. In the larva of
scarabids
and
termites
, illeum is pouch like for housing symbionts and acts as fermentation
chamber. Rectum contains
rectal pads
helping in dehydration of faeces and it opens out through
anus.
IV. GUT PHYSIOLOGY:
Primary functions of the gut is to digest the ingested food and to absorb
the metabolites. The digestion process is enhanced with the help of enzymes and microbes which
were produced by digestive glands and special cells.
