Question | Answer |
Aorta | pumps oxygen-rich blood to the body tissues |
Right Pulmonary Artery | carries oxygen-poor blood into the left lung |
Left Pulmonary Artery | carries oxygen poor blood into the left lung |
Right/Left Pulmonary Vein | carries oxygenated blood from the lungs to the left atrium of the heart |
Right Atrium | receives oxygen-poor blood from the body |
Left Atrium | receives oxygen-rich blood from the lungs |
Bicuspid Valve (Mitral Valve) | prevents back flow of blood from the left ventricle to the left atrium |
Right Ventricle | contracts to pump oxygen-poor blood along the pulmonary arteries to the lungs |
Left Ventricle | contracts to pump oxygen-rich blood along the aorta to the rest of the body |
Septum | the muscular wall that divides the heart into left and right halves |
Inferior Vena Cava | carries oxygen-poor blood from the legs and abdomen to the right atrium |
Superior Vena Cava | carries oxygen-poor blood from the head and upper body to the right atrium |
Semilunar Valves | either of two valves, one located at the opening of the aorta and the other at the opening of the pulmonary artery, each consisting of three crescent-shaped cusps and serving to prevent blood from flowing back into the ventricles |
Tricuspid Valve | prevents back flow of blood from the right ventricle to the right atrium |
