1. Draw an x-y axis graph. On the x-axis, there is increasing preload; on the y-axis, is stroke volume. Graph the Frank-Starling curve: How would preload affect stroke volume? Draw this graph.

  1. Draw an x-y axis graph. On the x-axis, there is increasing afterload; on the y-axis, is stroke volume. How would increasing afterload affect stroke volume? Draw this graph.

For # 3-5: Draw an x-y axis graph. On the x-axis, there is increasing muscle length; on the y-axis, there is muscle tension.

  1. Using this length-tension work diagram, graph the EW curve and then label all phases of the curve. What happens to the length and tension at each phase of this EW diagram?
