excretory cell development variant

Variations in the progression of a protokidney cell with an internal lumen that is suggested to collect and secrete salt solutions outward via the excretory sinus, over time from an initial condition to a later condition compared to control animals.

excretory secretory system morphology variant

Variations in the form, structure or composition of related tissues that allow the animal to secrete saline fluid and maintain a proper salt balance compared to control. In C. elegans, four cell types (1 pore cell, 1 duct cell, 1 canal cell and a fused pair of gland cells) make up the excretory system (Wormatlas).
