Section 2: Create a flow chart image showing the map of how blood flows through the heart Include each step starting in the right atria Include the names of valves that the blood passes through Section 3: Application 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.
