The left side in the heart has to be thicker and stronger since it has to pump blood throughout the whole body whereas the right area only pushes blood towards the lungs. 2 . Turn the heart so that the right area is with your right. Discover the large opening at the top of the heart following to the proper auricle. This is the opening for the superior filon cava, which usually brings blood vessels from the top half of the body to the correct atrium (the atria would be the top compartments in the heart). A little down and to the left in the large vena cava there exists another bloodstream vessel beginning. It potential clients into the right atrium. This is the inferior estrato cava, which brings blood vessels from the decrease tissues. You can even see one more blood boat next to the left auricle. This can be a pulmonary vein that brings blood vessels from the lung area into the left atrium. a few. Sticking straight up from the center of the heart is the most significant blood boat you can see. This can be the aorta, which in turn takes oxygenated blood from the left ventricle to the remaining body (the ventricles are the lower compartments of the heart). The aorta branches into more than one artery right after it leaves the heart. some. 4. Behind and to the left in the aorta there is certainly another significant vessel. This is actually the pulmonary artery which will take blood in the right ventricle to the lungs.
