why do the blood and dialysis flow in opposite direction
Hemodialysis The principle of hemodialysis is the same as other methods of dialysis; it involves diffusion of solutes across a semipermeable membrane. Hemodialysis utilizes counter current flow, where the dialysate is flowing in the opposite direction to blood flow in the extracorporeal circuit. Counter-current flow maintains the concentration gradient across the membrane at a maximum and increases the efficiency of the dialysis.
Ascaris lumbricoides Infections with these parasites are more common where sanitation is poor,[10] and raw human feces are used as fertilizer.
Wastewater If the wastewater contains human feces, as is the case for sewage, then it may also contain pathogens of one of the four types:[2][3]
