How dialysis treatment for kidney harm relies on an downstairsstanding of the principles of diffusion - Essay ExampleMaher states that an infection or physical injury to the kidneys send word affect the dialyzing ability of the kidneys. A malfunction of the human kidneys can lead to the accumulation of poisonous molecules such(prenominal) as urea in line of merchandise (Maher, 1989). A toxic level of urea in blood is fatal. A dialyzing machine works like the kidneys. The difference between a dialysing machine and the human kidneys is the move up dialysis, which returns small molecules like glucose to the body. The natural kidneys perform endocrine function, which is not possible in the dialysis machine (Maher, 1989).Chung lee (2006) explains that dialysis is a short-term treatment option to sustain the lives of patients waiting for a kidney transplant. In 2006, research showed that in the globally there were over 1 million patients dependent on dialysis. In the United States 50 6,256, citizens were under dialysis treatment.

There ar deuce dialysis procedures available for patients experiencing renal problems hemodialysis and peritoneal dialysis. Hemodialysis involves pumping the patients blood through and through an artificial dialysis membrane present in the dialysis machine. The waste products in the patients blood circularize through the membrane to the dialysate. This movement occurs due to the presence of a concentration gradient between the two media.In peritoneal dialysis, the peritoneum in the abdominal cavity works as the dialysis membrane. The peritoneum has a dense capillary vessel network, which makes it a suitable media for the dialysis procedure. The dialysate is pumped to the abdominal cavity via a catheter. In peritoneal dialysis, toxic substances fathom to the dialysate through the blood capillaries semi permeable me mbrane (Maher, 1989). Cheng explains that a patient can self-administer peritoneal dialysis.
