The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs.

Low Blood Pressure: Unfortunately, dialysis is an exchange of blood between the patient and the hemodialysis machine. At certain times, too much blood can be taken from a patient that leads to an acute drop in blood pressure. This decrease in blood pressure likely leads to some people passing out while on the hemo-dilaysis machine. ...Read moreSee 1 more doctor answer

Artificial kidney: The principle of dialysis machine is hard to explain in 400 characters. Like a human kidney, it filters impure blood under pressure; excess water is removed; blood toxins (prea, phosphorus, and many others) diffuse out in to the dialysate (the clean artificial fluid put in to the machine); some electrolytes might diffuse back in to blood. The relatively clean blood diffuses is returnd to the patnt. ...Read more
Countercurrent flow: The dialysis machine is based on pumps that move blood through the artificial kidney (a filter) while making dialysate (a mixture of water and chemicals) to move the opposite direction through that filter. The blood and dialysate are separated by a semipermeable membrane in the filter. By moving in opposite directions, the waste products in the blood tend to go into the dialysate cleaning the body. ...Read more

Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure.
