What is the importance of the coronary artery? What happens when the vessels become clogged? What would be the difference

Section 1: Create a flow chart image showing the map of the electrical activity of the heart (begin with the SA node) Include each step the electrical activity travels as it goes through the heart. 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. 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,…

for its oxygen then it may die, forming rct. The severity of this condition depends on the precise location of the occlusion, which downstream tissues are involved, and how large an area of tissue dies. Use Figure 4.9 as a reference and list the flow of blood through both circuits in order, beginnng with the right atrium (don't forget to include the heart valves). 1. If an embolus breaks off in a systemic vein in the leg, it would be able to pass through: It would occlude: 2. If an embolus formed in the left ventricle, it would be able to pass through: 3. It would occlude: 4.

Which valve does blood pass through on its way to the right ventricle? :_______________ Which vessel carries oxygenated blood in the pulmonary circuit? :_______________ Which chamber of the heart receives blood returning from the body? :_______________ Which chamber of the heart sends blood to the lungs? :_______________ Which valve prevents backflow of blood into the left ventricle? :_______________ Which vessels carry oxygen-rich blood? :_______________ Which vessels carry oxygen-poor blood? :_______________ Which vessels carry blood away from the heart? :_______________ Which vessels carry blood back to the heart? :_______________ Which valve does blood pass through in order to enter the pulmonary artery? :_______________ Where does blood in the right atrium go next? :_______________ Where does blood in the left ventricle go next? :_______________? Where does blood in the vena cava go next? :_______________ Is blood in the pulmonary vein oxygen-rich or oxygen-poor? Where does it go…

Damage to the AV node in humans…….. would block conductance between the bundle branches and the Purkinje fibers. would have an effect on blood pressure monitors in the aorta is a major contributor to heart attacks. would disrupt the rate and timing of cardiac muscle contractions. would block the transmission of the electrical impulse from atria to ventricles
