Assignment

Today we will be completing work for the pass section of the cardiovascular assignment.  The pass criteria is to 'take measurements of the cardiovascular system, relating the resultsto the function of the cardiovascular system.'
To do this we will complete the following activities and write up your results in a word document:

1. Take your resting heart rate.  Use the link below if you are unsure about finding your pulse, and record the amount of beats per minute in a table.  Do this three times and take an average, all while sitting still and not moving too much. - http://www.nhs.uk/chq/Pages/2024.aspx?CategoryID=52&SubCategoryID=145
2. Do 30 seconds of exercise, and then take your heart rate again.  You could do star jumps in class, or quickly walk up and down the stairs twice outside the room.  As soon as you finish, take your heart rate in beats per minute.  Repeat the exercise once more and measure your pulse again.  Record both numbers and then take an average.
3. Compare the two averages from your table.  How are they different? Why might this be? Explain why your pulse is generally lower when resting, and higher when exercising. - http://www.livestrong.com/article/345679-why-does-my-heart-rate-get-really-high-when-exercising/
4. List and describe some other factors that can affect heart rate - http://www.heartmonitors.com/exercisetips/changing_heartrate.htm Explain WHY these factors cuase changes in heart rates.
