Describe what is occurring in the heart (regarding contraction) during each step of the electrical activity. In other words, what does the electrical activity indicate is happening in the heart (atria contraction, ventricle contraction/relaxation, etc).
Also, explain how these contractions lead to proper blood flow sending blood to the appropriate areas for oxygen delivery.
This section should be no more than one page in length (double spaced for APA format) and should give detailed information about how these three aspects of the heart (electrical activity, contraction, blood flow) work together to serve our tissues.
Include at least two references in addition to any course materials.
*Note: images/flow charts must be original. If they are from a textbook or other source you will receive a zero for this assignment. Images may be created in powerpoint or using online resources such as canva.com. Consider that these images may be something you would see in a presentation to explain the electrical activity and/or blood flow through the heart.
