Experiment Results Predict Question: Predict Question: If you increase the flow tube radius, what will happen to the pump rate to maintain constant pressure? Your answer : a. The pump rate will increase. Stop & Think Questions: When the piston of the pump reaches its lowest point, the volume remaining in the pump is the You correctly answered: b. end systolic volume. If you increase the right flow tube radius, what will happen to resistance and flow rate? You correctly answered: b. Flow rate will increase and resistance will decrease. If the left flow tube represents the pulmonary veins, what does the left source beaker represent?

Case Study

...important cell membrane processes of diffusion, osmosis, filtration, and active transport. The simulations will allow you to alter conditions to show the effect of concentrations, pore size, pressure, carrier, and ATP have on movements of materials through the cell membrane. Purpose: To conduct experiments showing the effects of concentration, ions, and particle size of movement through the cell membrane. Materials: Lab manual, PhysioEx 9.0 Procedure: Cell Transport Mechanisms and Permeability in the lab manual. You will also need the PhysioEx 9.0 CD for this lab. Read over exercise overview and introduction. Complete the following questions from the exercise as you complete the simulation exercises. Go to Exercise 1 Cell Transport Mechanisms and Permeability on the CD. Follow the directions and complete each part. Answer questions or fill in tables as you proceed through the experiment. Place your answers in the spaces provided below. Submit your lab in Moodle. Activity 1. Simple Diffusion Chart 1 |Chart 1 Dialysis Results(average diffusion rate in mM/min | | |...
