PHYSIO EX 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the

Lab 28B: Endocrine System Physiology Computer Simulation Introduction The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In

Cardiovascular Physiology and Blood Pressure July 27‚ 2009 BY 409L - LW Blake Perry Lab Partners: Jennifer Rastegar and John Riopka Abstract This experiment was designed to observe a baseline heart rate and blood pressure and to examine various modifications of the two. This experiment utilized both the BiopacPro and PhysioEx computer programs. The PhysioEx program was used to simulate a heart rate and modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure;
