How do worms wee?
They certainly don’t have miniature urinals lying about! Worms actually release their water waste through the external pores of their body. The organ which does the separation of this waste is called nephridium, which is basically a long winded tube with a funnel end inside the body and the other end connected to a pore leading to the external world.
Almost each segment of the worm contains a pair of nephridum. The nephridium acts in a very similar way our kidney acts. It first collects the liquid in the body through a funnel. The liquid passes then through the tube, the nutrients being reabsorbed back in to the surrounding blood vessels, and the remaining waste liquid is discharged out of the pores!
