Question

Insects pass their uric acid through the alimentary canal
Why?

Riffat Jahan · Accepted Answer

Its not like that Insects do not pass their uric acid through
the whole alimentary canal
Most of the insects excrete nitrogenous wastes as uric acid in
the form of pellet or paste with a minimum loss of water and are
called uricotelic animals
To do this, undigested food particles in the hind gut of insects
join uric acid from Malphigian tubules( excretory structures of
most of the insects) to form fecal pellets The rectum absorbs most
of the water in this waste matter, and the dry pellet is then
eliminated through the anus, without separate release of
nitrogenous wastes as occur in most ureotelic animals
