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 10: Acid/Base Balance Worksheet Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.38 2. At 40 seconds‚ pH = 7.38 3. At 60 seconds‚ pH = 7.38 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No. 5. Was the pH level always within the “normal” range for the human body? Yes. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No. Activity 2a: Hyperventilation

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

PhysioEx – Exercise 9 Activity 1: 1. excretion and regulation 2. glomerular capillaries (glomerulus) & Bowman’s capsule 3. 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

Premium Diffusion Osmosis Molecular diffusion
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
