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

made a slightly larger action potential than the unheated rod. 5. Describe the types of stimuli that generated an action potential. The different stimuli that generate an action potential are electrical‚ chemical‚ mechanical‚ and thermal. 6. If you were to spend a lot of time studying nerve physiology in the laboratory‚ what type of stimulus would you use and why? I would use chemical stimulation. I would want to see what different chemicals would cause an action potential versus chemicals

the efferent radius decreases the glomerular filtration rate. Increasing the efferent radius allows more blood drainage out of the glomerulus and that decreases the amount of blood to be filtered so the glomerular filtration rate will decrease. 6. How did decreasing the efferent radius affect glomerular filtration rate? >> Decreasing the efferent radius increases the glomerular filtration rate. The constriction of the efferent radius will limit blood drainage out of the glomeruli and

During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as
