OSMOSIS LAB BACKGROUND INFORMATION. Dialysis tubing is being used to model a plasma membrane. Isotonic solutions are solutions that have the same concentration of solutes on both sides of the membrane. Hypertonic solutions are solutions that have more solute to the one with less solute. Hypotonic solution are solutions that have less solute to the one with more solute. RESEARCH QUESTION:which dialysis tubing will gain the distilled water and which one will loss its content

the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We tied off one end of the dialysis tubing to create a bag‚ filled it with distilled water‚ and tie of other end to close. The bag is carefully blotted to remove any water spilled during the filling and

Dialysis and kidney transplantation are treatments for End Stage Kidney Failure. There are two types of dialysis: hemodialysis and peritoneal dialysis. As the kidneys lose their ability to function‚ fluid‚ waste products‚ and electrolytes begin to build up in the blood. Dialysis is generally planned when their kidney function is <15 percent of normal. KIDNEY TRANSPLANTATION Kidney transplantation is considered the treatment of choice. Quality of life and survival are often better than in people who

Houston Dialysis Center is a department of Houston General Hospital‚ a full-service‚ not-for-profit acute care hospital with 325 beds. The bulk of the hospital’s facilities are devoted to inpatient care and emergency services. However‚ a 100‚000 square-foot section of the hospital complex is devoted to outpatient services. Currently‚ this space has two primary uses. About 80 percent of the space is used by the Outpatient Clinic‚ which handles all routine outpatient services offered by the hospital

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

working in a hospital setting; going on 14 years. Dialysis technicians work with people whose kidneys no longer work properly or at all. I operate machines that remove wastes‚ salt‚ and extra water from patients’ blood while keeping safe levels of certain chemicals. Dialysis patients generally are on the machine for about four hours‚ three times a week. My job as a technician is to prepare patients for dialysis‚ monitor them and the machine during dialysis‚ give local anesthesia‚ monitor patients’ progress

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III.

Disease (ESRD)‚ it is a direct result of chronic kidney disease. It is at this point that the kidneys can no longer remove toxins from the body through urine. There is no cure for CKD but requires treatment for survival‚ either a kidney transplant or dialysis. A kidney transplant is a treatment not a cure for end stage renal disease patients. However‚ it the doctor thinks this is an option then patients are medically evaluated at a transplant hospital. Evaluation is done by x-rays‚ blood work and other

Secondly‚ osmosis was to be observed to gain a proper understanding of how the principal of dialysis functions. Procedure: 1. Make a water bath assembly by doing the following: a. Half-fill the 100-mL beaker with cool tap water. b. Place crushed ice in the beaker so the water level is just below the top of the a. beaker
