pathway

superior vena cava and inferior cava is where deoxygenated blood enters → right atrium → from the right atrium → right ventricle through the tricuspid valve → from the right ventricle through the pulmonic valve → pulmonary artery → lungs → pulmonary vein empties deoxygenated blood → left atrium → mitral valve → left ventricle → through aortic valve → aorta → delivery of oxygen to the body
