Excretory Organs Across Taxa: Flame Cells, Malpighian Tubules, Nephridia

State

Non-vertebrate excretion solves filtration without the nephron's three-step architecture, instead using taxon-specific organs — flatworm flame cells, insect Malpighian tubules, and annelid nephridia — each achieving the same filtering goal by a different structural route.

Show

Malpighian tubules concentrate uric acid before it exits with feces, conserving water on land.

Watch for

These organs solve the nephron's same problem without sharing its filtration-reabsorption-secretion structure.
