Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens

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

Respiratory System Mechanics Simulation Lab Activity 1: MRV __7500__ ml/min =500 tv x 15bmp Does expiratory reserve volume include tidal volume? Explain. Expiratory reserve volume (ERV) does not include tidal volume. Expiratory reserve volume is the amount of air that can be expelled after a normal tidal exhalation. This means that tidal volume is not included in the ERV measurement. Activity 2: FEV1‚ as % of VC Radius FEV1 Vital Capacity FEV1% 5.00 3541 4791 73.90 4.50
