Introduction: In this experiment‚ the experimenter tried to organize the order of 5 unknown solutions by using dialysis tubing lab. The 5 solutions were put into each tubing bag that were all tied up and placed into each beaker of water and waited to look for the change in masses of each bag. The type of solution that were put in the tubing bag are the independent

Direction and concentration gradients Bradley Benton ABSTRACT In this experiment‚ we will investigate the effect of solute concentration on osmosis. A semi‐permeable membrane (dialysis tubing) and sucrose will create an osmotic environment similar to that of a cell. Using different concentrations of sucrose (which is unable to cross the membrane) will allow us to examine the net movement of water across the membrane. INTRODUCTION A major determinant of diffusion in a biological system is membrane

renal disease is when there is a permanent loss of total renal function. End-stage renal disease‚ is also known as chronic kidney disease (CKD)‚ with five stages. The fifth stage is the most severe stage‚ this is when the patient needs to begin dialysis‚ or be transplanted to survive. The Center for Disease Prevention and Control ranks End stage renal disease the ninth leading cause of death in the United States ("Center For Disease Control And Prevention"‚ 2010).

2009). The number of patients suffering from CRF in United Kingdom (UK) is rising rapidly. Ferenbach and Wood (2005‚ p.16) state that in UK‚ about 6000 people are commencing dialysis treatment per year. Fluid overload is a frequently observed finding in renal failure patients. About one third of the patients receiving dialysis for Chronic Renal Failure have fluid overload despite advice to restrict their oral fluid intake (Roderick‚ et al 2004).

fail‚ treatment is necessary‚ and there are only two options: a kidney transplant or dialysis. Dialysis first became a practical treatment in the 1960’s. There are two main types of dialysis‚ hemodialysis and peritoneal dialysis. Both types of dialysis filter blood of harmful wastes‚ extra salt‚ and water. Hemodialysis does this with a machine. Both require a special diet and both types have risks and benefits. Dialysis is not always permanent‚ it depends on if the disease is chronic (long-term) or acute
