Utsarjan (excretion)

There are very few srotasas performing this function. The mutravaha
srotasa, purishavaha srotasa are involved in the excretion of mutra and purisha
respectively. All these srotasas and their functions are very essential to maintain the
homeostasis as well as the proper metabolic status of the body.
