Heart Functions Essay

1.What do you notice about the sizes of the four chambers? Annotate the measurements you have preserve onto your drawing. The ventricles are much bigger than the atria and the left ventricle is bigger than the reform ventricle. Left atrium argue 0.4cmLeft ventricle wall 1.4 cmRight atrium wall 0.2 cmRight ventricle wall 0.6 cm2.The left ventricle has a much thinker wall than the right ventricle explain wherefore this is. The left ventricle has a much thicker wall than the right ventricle because the left ventricle has to meat blood to the whole body while the right ventricle only has to pump blood to the lungs.3.What is the function of the tendinous cords attached to the bicuspid and tricuspid valves? The tendinous cords attached to the bicuspid and tricuspid valves hold the valves in place and prevent them from turning inside out.4.Explain how blood flow in the sprightliness moves in one direction only and survey the movement of a single red blood cadre through the heart. T he valves in the heart prevent the back flow of blood on the heart because they close shut whenever the blood starts flowing in the wrong direction. A deoxygenated red blood cell coming from the body would enter the heart from the nervure cava into the right atrium.It would then go into the right ventricle through the tricuspid valve. From the right ventricle, it would be pumped to the lungs through the pulmonary artery. The red blood cell would be oxygenated in the lungs and would return to the left atrium through the pulmonary vein. From the pulmonary vein, it would go through the bicuspid valves into the left ventricle and the left ventricle would pump it through the aorta to the rest of the body.5.What is the function of the coronary arteries?The coronary arteries supply the cardiac muscle with the blood and in turn oxygen they need to contract.
