1. Hemodialysis: In hemodialysis, a machine filters blood outside of the body and returns it to the patient. An access point, usually a port in the arm, allows blood to flow out of the body and through a dialysis machine. In the machine, blood flows through a filter or set of filters that remove waste and excess fluids. This process typically takes three to four hours and is typically done three times a week.

2. Peritoneal Dialysis: Peritoneal dialysis involves implanting a catheter into the abdomen, where a sterile solution is introduced into the patient's abdominal cavity. The solution is then drained slowly, after it has absorbed wastes and excess fluids from the blood. The amount of time the solution stays in the body depends on the patient's specific needs. Peritoneal dialysis can be done at home or in a clinic setting.

Dialysis is a life-saving treatment for patients with kidney disease, and it is an essential component of healthcare. Dialysis units are located in hospitals, clinics, and specific treatment centers. Dialysis technicians, nurses, and doctors play vital roles in providing care and support for patients during their dialysis treatment.
