Final answer:
Filtration is the passive, non-selective renal process in urine formation where solutes and fluids are forced through the filtration membrane by hydrostatic pressure.
Step-by-step explanation:
The passive, non-selective renal process in urine formation in which solutes and fluids are forced through the filtration membrane by hydrostatic pressure is Filtration. Filtration occurs in the renal corpuscle and is the first step in urine formation.
