Explain the significance of the thickness of the left ventricular wall.
The right ventricle wall is small and thin containing deoxygenated blood. The left is just the opposite. The left ventricle is larger and thicker making it stronger than the right, but containing oxygenated blood. However, since it is pumping blood all around the body, it is at a more forceful rate (Oxford Journals, 2016).
The major coronary vessels are on the surface of the heart. What is the advantage of that location?
The heart contains major coronary vessels on the surface. The location of it helps to supply oxygen to different areas of the heart. Since they are on the surface the heart's efficiency increases as it decreases other potential problems. However, if these vessels were located inside of the heart it may result in a decrease in strength of the heart's wall. The vessel's location on the surface has its advantages …show more content…
To maximize its full efficiency of contraction the conduction system of the heart contains substantial atrial to ventricular delay allowing the atria to empty their substances into the ventricles, however, simultaneous contraction could result in inefficient filling and lead to backflow. The atria are electrically isolated from the ventricles and are only linked by the atrioventricular node (AV node) as it momentarily delays signals. The AV node can be found in the ventricles situated in the septum as it assists in forcing the blood to the lungs and other parts of the body. However, it is not possible for a direct transmission of an impulse from the SA node to the ventricle to occur because of the discontinuity of muscles between the atria and ventricles. The transmission from the SA node can stimulate AV nodes to produce new impulses for ventricles therefore acting as a pacesetter (NIH,
