Introduction/Tech Support

PowerPhys is a program of activities developed to simulate laboratory experiences that illuminate important physiological processes and their implications for maintaining homeostasis.

A screenshot shows a window titled, Power P h y s v 3.1. On the top right corner, two options, Take a tour and Help, are displayed. The left side of the window shows the illustration of a human heart, below which a laboratory report is displayed. Beside the illustration of the heart, the following four names are listed: Connie Allen, Valerie Harper, Thomas Lancraft, and Yuri Ivlev. The right side of the window shows a numbered list of 14 sub-headings and a description below each sub-heading. The sub-headings and their corresponding descriptions are as follows: Sub-heading 1: Enzyme Activity; Effect of p H on Enzyme Activity, Effect of temperature on enzyme activity, Effect of substrate concentration on enzyme activity. Sub-heading 2: Twitch contractions and summation; Measurement of Threshold stimulus, Effect of muscle fiber length on force of contraction, Effect of stimulation frequency on contraction. Sub-heading 3: Recruitment and Isotonic and Isometric Contractions; Comparison of Motor Unit Activation During Concentric and Eccentric Contractions, Recruitment During Isometric Contractions. Sub-heading 4: Action Potentials; Effect of Stimulus Strength on Action Potential Generation, Effect of Frequency of Stimulation on Action Potential Generation. Sub-heading 5: Blood Glucose Regulation; Effect of Fasting and Carbohydrates on Blood Glucose, Kotono, Insulin, and Glucagon Concentrations. Sub-heading 6: Effect of Exercise on Cardiac Output; Effect of Exercise on Cardiac Cycle Length, E D V, E S V, H R, S V, and C O. Sub-heading 7: Effect of Exercise on Arterial Pressure and Vascular Resistance; Effect of Exercise on Systolic and Diastolic Blood Pressure, Mean Arterial Pressure, and Systemic Vascular Resistance. Sub-heading 8: Respiratory Volumes; Effect of Exercise on Breathing Rate, Lung Volumes, Lung Capacities, and Minute Ventilation. Sub-heading 9: Regulation of Pulmonary Ventilation; The Effect of Hypercapnia on Pulmonary Ventilation, The Effect of Hypoxemia on Pulmonary Ventilation. Sub-heading 10: Influence of Fluid Intake on Urine Formation; Effect of Fluid Intake on Urine Production, Plasma Osmolanty, and Urine Osmolarity. Sub-heading 11: Homeostatic Imbalances of Thyroid Function; Thryoxine (T 1), Thyrod Stimulating Levels (T S H), and Thyroid Images (Radioactive Iodine Uptake Images) in Patients with Primary Hypothyroidism, Secondary Hypothyroidism, and Hyperthyroidism. Sub-heading 12: Hematocrit and Hemoglobin Concentration and Blood Typing; Effect of Attitude on Hematocrit and Hemoglobin Concentration, A D O and R h Typing in Family Members. Sub-heading 13: Acid-Base Balance; Types of Acid-Base Imbalances and Compensatory Changes. Sub-heading 14: Effect of Dietary Fiber on Transit Time and Bile; Effect of Dietary Fiber on Transit Time, Effect of Dietary Fiber on Bile Adsorption and Reabsorption.

Each activity progresses through six stages, beginning with a review of important information and ending with the completion of a laboratory report.

Data that is collected in each laboratory is provided within ranges, so that each time you perform the simulation you will get different data sets. All data sets will lead to the same conclusions, but because it changes each time you engage in a simulated activity, you must complete each activity from Pre-lab reporting through the Laboratory Report in one laboratory session.

Clicking or tapping on the "Take a Tour" Button on the home page will provide an overview of the functionality and navigation of PowerPhys. Alternatively, click or tap on a specific topic within Help to review the details of that feature.

Home

Home button

The Home button will bring you back to the home page of PowerPhys where the list of activities appears. Do not return to the home page if you have not completely populated the tables in data collection, since doing so will cause you to lose your data.

If you choose Home and your data tables have been fully populated, your data will be saved and you will not need to begin the experiment again.

Reset All

Reset buttonA screenshot shows a pop-up box on a window which reads, Your data for the entire module, including the laboratory report, will be deleted. Data collection will refresh with a new data set. The pop-up box displays two buttons, Cancel and O K, below the text. In the background, the window displays an illustration of a laboratory setup and the data in a table below it. This illustration shows a data acquisition unit, a monitor, and a few other instruments connected.

The Reset All button allows you to start a section over again. A pop-up box will ask you if you wish to proceed, since doing so will cause you to lose your data for the entire module.
