IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

The Effect of Osmosis on Potatoes/ Diffusion of Molecules through Benedicts Test of Dialysis dubing Introduction The focus of the lab on September 16‚ 2013 was Diffusion and Osmosis. Osmosis is a process in which the molecules of a solvent diffuse from an area of high concentration to an area of lower concentration‚ through a semipermeable membrane. Small solute molecules and water molecules can move freely through a selectively permeable membrane‚ but large molecules may pass through more

kidney failure‚ you need dialysis because you have lost eighty-five to ninety percent of your kidney function. Dialysis patients can still live an active and social lifestyle. Dialysis keeps your body in balance by removing waste‚ salt‚ and extra water. It also helps control blood pressure‚ keeping a safe level of chemicals in the blood‚ such as potassium‚ sodium‚ and bicarbonate. There are two different types of dialysis treatment options hemodialysis and peritoneal dialysis. Hemodialysis which is

arteriosclerois‚ obstructions to the urinary system‚ toxins‚ trauma‚ or infection. One of the most common treatments for ESRD is hemodialysis. This uses a kidney dialysis machine to filter waste products and excess fluids from the blood. During hemodialysis the blood flows from the body through and intravenous access such as a shunt or fistula‚ to a dialysis machine‚ where it passes through a dialyzer (filter). The clean blood is then returned through the access. This process generally takes two to four hours

prevalence of these diseases continue to rise daily. In conjunction with the aging population‚ these are the most common causes of kidney disease. Patients with end stage renal disease will require either transplantation or dialysis. With the rising cost of health care‚ peritoneal dialysis has been identified as being potentially more cost effective than in-center hemodialysis‚ but it is not the treatment of choice by most doctors for their patients. Treatment of end stage renal disease is challenged by

Reimbursement for those with ESRD receiving any form of dialysis; hemodialysis (HD)‚ peritoneal dialysis (PD)‚ continuous ambulatory peritoneal dialysis (CAPD) or continuous cycling peritoneal dialysis (CCPD)‚ uses Medicare as its payer. In 1973‚ health care changed drastically for those suffering from ESRD. Regardless of age‚ every citizen would be entitled to coverage under

the arm and hands are either not available or are exhausted due to failure of fistulas previously created in the arms. A fistula takes many weeks to mature‚ on average perhaps 4–6 weeks. During dialysis treatment‚ two needles are inserted into venous column of the fistula‚ one draws blood to the dialysis machine and the other one to return it to venous circulation. While inserting the needles orientation of the normal flow is taken into account. The "arterial" needle draws blood from the "upstream"

Chronic renal failure is a worldwide public health problem. Millions of Americans are affected by this disease each year. It is a common condition in which there is progressive loss of kidney functioning. The loss of function usually takes months or years to occur‚ sometime not appearing until kidney function is less than one-tenth of normal. The kidneys have the important job of filtering‚ wastes and excess fluids from your blood‚ which are then excreted in the urine (Huether‚ 2012). When the kidneys
