At 20 seconds‚ pH = 7.48 2. At 40 seconds‚ pH = 7.52 3. At 60 seconds‚ pH = 7.65 4. Maximum pH = 7.65 5. Did the pH level of the blood change at all during this run? If so‚ how? Yes it did‚ when the breathing rate changed the pH began to rise. 6. Was the pH level always within the “normal” range

Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? NO 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5. Record this maximal voltage here:

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
