Answer 1

kidneys are vital organs for survival.several factors like infections,injury,very high blood pressure, very high blood sugar or ristricted blood flow to kidneys.this leads to accumulation of poisonous wastes in the body and leads to death.Dialysis machine is used to filter the blood of a person when both kidneys are damaged.This process is called hemodialysis.In this process blood is taken out from the main artery, mixed with an anticoagulant,such as heparin,and then pumped into the apparatus called dialyzer.in this apparatus blood flows through channels or tubes.These tubes are embedded in the dialyzing fluid.The memberane separates the blood flowing inside the tube and dialyzing fluid,which has the same composition of plasma, except the nitrogenous wastes.

As nitrogenous wastes are absent in dialyzing fluids these substances from the blood move out freely,there by cleaning the blood of its wastes.This process is called dialysis.

Answer 2

Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of purifying the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure. Hemodialysis is one of three renal replacement therapies (the other two being kidney transplant and peritoneal dialysis). An alternative method for extracorporeal separation of blood components such as plasma or cells is apheresis.

Hemodialysis can be an outpatient or inpatient therapy. Routine hemodialysis is conducted in a dialysis outpatient facility, either a purpose built room in a hospital or a dedicated, stand-alone clinic. Less frequently hemodialysis is done at home. Dialysis treatments in a clinic are initiated and managed by specialized staff made up of nurses and technicians; dialysis treatments at home can be self-initiated and managed or done jointly with the assistance of a trained helper who is usually a family member.
