Document Summary
Evidence of hyperkinetic state in children with elevated blood pressure (chirico et al 2014) Located in the mediastinum (middle of thorax) top of heart upper right chest, below second rib and right of sternum: apex lies just above diaphragm. Chambers of the heart: atria, top of the heart, think walls, separated by interatrial septum, right atrium, receives deoxygenated blood from venous system. Inferior vena cava, superior vena cava, coronary sinus: tricuspid valve. Left atrium: recieves oxygenated blood from pulmonary veins, 2 mm thick (thicker than right atrium, bicuspid (mitral) valve, ventricules. Left ventricle: high pressure chamber pumps blood to entire body, longer and thicker than right ventricle (3 x thicker, works the hardest, first to get weak and fail. Which chamber receives deoxygenated blood from the periphery: left ventricle, right atrium, right ventricle, left atrium. Which chamber of the heart pumps blood to systemic circulation: left atrium, right atrium, left ventricle, right ventricle.
