e.What is the long-term prognosis for the disease?

Prepare a multimedia presentation to inform your classmates of what you have learned. Use bibliographic citations of the sources in your class presentation. Below is a web site to get you started:

PubMed –National Library of Medicine Search Service http://www.ncbi.nlm.nih.gov/PubMed/

2. Open-heart surgery has become a routine procedure to correct certain problems with the heart. Conduct an Internet search to find out:

a.How many different kinds of surgical procedures are in use today?
b.What might be the cause for the illness the surgery is correcting?

Application Software

Activity 9C – Use a spreadsheet program to make your data table as shown in this activity. Record the data in the spreadsheet as you perform the activity. Use the mathematical functions of the spreadsheet to do the calculations for finding the average heat rate for each exercise time for your group. Record the rest of the class averages in your data table. Use the graphing function to plot a graph of heart rate and total number of minutes as directed in the activity. Use this graph to share your information with classmates. Print the final spreadsheet with all calculations, and secure it in your SCIENCE PROBE Logbook where you will answer the discussion questions.
