Left Atrium - This chamber receives oxygenated blood from the body before passing it onto the left ventricle, Left Ventricle - This chamber pumps blood into the aorta which takes the oxygenated blood around the body., Right Ventricle - This chamber pumps blood into the pulmonary artery, before directing the blood to the lungs, Tricuspid Valve - This is located between the right atrium and right ventricle and prevents the back flow of blood., Aortic/semilunar valve - This valve lies between the left ventricle and the aorta preventing the back flow of blood., Pulmonary Veins - Carries oxygenated blood from the lungs to the left atrium, Superior Vena Cava - Is a large but short vein that carries deoxygenated blood from the upper half of the body to the right atrium, Aorta - The largest artery in the body, originating form the left ventricle it carries oxygenated blood to all parts of the body, Bicuspid Valve - This is situated between the left atrium and left ventricle and prevents the backflow of blood., Septum - Seperates left and right side of the heart, Pulmonary Artery - Carries deoxygenated blood from the heart to the lungs. It is the only artery in the body that carries deoxygenated blood, Inferior Vena Cava - Is a vein that carries deoxygenated blood from the lower half of the body to the right atrium, Right Atrium - This chamber receives deoxygenated blood from the body before delivering it to the right ventricle, Sinoatrial Node (SA Node) - Initiates the electrical impulses to stimulate contraction., Atrioventricular Node (AV Node) - Slows down the electrical current before it is passed to the ventricles., Bundle of His - Transmits electrical impulses from the atrioventricular node to the ventricles., Purkinje Fibres - Transmit electrical signals rapidly, which allows the ventricles to contract in a coordinated manner., Chordea Tendineae - Heart Strings. These are strong, fibrous strings in the heart that connect the heart's Bicuspid and tricuspid valves to the heart wall,
