Natalie Salaverria 01/21/11 LAB EXERCISE I After the first exercise : Simulating Simple diffusion Which Materials diffused from the left beaker to the right beaker? NaCl ‚ Urea ‚ Glucose Which did not ? Albumin Why ? Albumin’s Composition or charge was too great to diffuse through the membrane. After the 2nd activity : Simulating Dialysis What happens to the urea concentration in the left beaker (the Patient)? It diffused to the right beaker Why does this occur? The excess

Exercise 6: Cardiovascular Physiology Worksheet Assignment Due: Week 6 Electrical Stimulation Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? I did not see a change in the trace 2. Why or why not? This is because it needs more stimulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? This is because there is double stimulation. 5. Describe the change you see in the trace. How does it differ from the baseline

prediction because I predicted that the resting membrane potential would become less negative. 3. The extracellular Na+ did not alter the membrane potential in the resting neuron because the Na+ channels were mostly closed. 4. Na+ and K+ both have a relative permeability of 0 voltage outside a resting neuron and a relative negative permeability inside a resting neuron. 5. A change in Na+ or K+ conductance would affect the resting membrane potential because if the membrane is permeable to a particular

The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased
