| Question | Answer |
|---|---|
| Aorta | The largest artery that carries oxygen-rich blood from the left ventricle to the body. |
| Left Ventricle | Pumps oxygen-rich blood into the aorta and out to the body. |
| Right Ventricle | Pumps oxygen-poor blood to the lungs through the pulmonary artery. |
| Left Atrium | Receives oxygen-rich blood from the lungs |
| Right Atrium | Receives oxygen-poor blood from the body. |
| Coronary Artery | Supplies oxygen-rich blood to the heart muscle itself. |
| Apex | The pointed bottom tip of the heart |
| Superior Vena Cava | Brings oxygen-poor blood from the upper body to the right atrium. |
| Inferior Vena Cava | Brings oxygen-poor blood from the lower body to the right atrium. |
| Pulmonary Artery | Carries oxygen-poor blood from the right ventricle to the lungs. |
| Pulmonary Veins | Carry oxygen-rich blood from the lungs to the left atrium |
| Chordae Tendineae | Heart strings” that help keep heart valves from flipping backward |
| Papillary Muscles | Muscles in the ventricles that pull on the chordae tendineae to control valve movement. |
| Septum | Wall that separates the right and left sides of the heart. |
| Tricuspid Valve | Valve between the right atrium and right ventricle |
| Bicuspid/Mitral Valve | Valve between the left atrium and left ventricle. |
| Aortic Semilunar Valve | Valve between the left ventricle and the aorta. |
| Pulmonary Semilunar Valve | Valve between the right ventricle and the pulmonary artery. |
| Brachiocephalic Artery | First major branch of the aorta that supplies blood to the right arm and head. |
| Left Main Coronary Artery | Main artery that branches to supply the left side of the heart. |
| Left Anterior Descending (LAD) Coronary Artery | Supplies blood to the front of the left side of the heart. |
| Circumflex Coronary Artery | Supplies blood to the left atrium and side/back of the left ventricle. |
| Left Posterior Descending Coronary Artery | Supplies the back part of the left ventricle |
| Right Coronary Artery | supplies blood to the right side of the heart. |
| Posterior Descending Coronary Artery | Supplies blood to the bottom/back of the heart; usually branches from the right coronary artery. |
