When we exercise our heart rate goes up. Why does this happen? be complete in your answer, I’m looking for you to demonstrate what you learned. Start with what’s happening in the muscles cells and go from there.  

Which of the following is NOT one of the three (3) main factors influencing resistance to blood flow?

We said that a convenient way to think about blood pressure was to use the equation BP=CO x R (resistance). So when we are exercising, our heart rate can easily double, resulting in increased cardiac output (CO). Why doesn’t blood pressure also increase significantly? 

The Semilunar valves close as a result of:

Explain stroke volume in terms of EDV and ESV. How would an increased afterload change stroke volume?

If the SA node is damaged and AV node takes over setting the pace of the heart, the resulting heart rate would be:

Depolarization of the SA node stimulates depolarization of the muscle cells of the left and right atria.
