Heart Flashcards
| Term | Definition |
|---|---|
| Aorta | the largest artery in the body, responsible for carrying oxygen-rich blood from the heart's left ventricle to the rest of the body |
| Left Ventricle | the lower-left chamber of the heart that receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta |
| Right Ventricle | a chamber in the heart that pumps deoxygenated blood to the lungs to pick up oxygen |
| Left Atrium | one of the four chambers of the heart that receives oxygen-rich blood from the lungs and pumps it into the left ventricle. |
| Right Atrium | one of the four chambers of the heart, located in the upper right side. Its main function is to receive oxygen-poor blood from the body and pump it into the right ventricle |
| Coronary Artery | the blood vessels that supply the heart muscle with oxygen-rich blood. |
| Apex | the pointed or narrowed tip of a cone-shaped or rounded organ. |
| Superior Vena Cava | large vein that carries deoxygenated blood from the head, neck, arms, and upper chest to the right atrium of the heart |
| Inferior Vena Cava | carrying deoxygenated blood from the lower half of the body—including the legs, abdomen, and pelvis—back to the right side of the heart |
| Pulmonary Artery | blood vessels that carry oxygen-poor blood from the right side of your heart to your lungs |
| Pulmonary Veins | a blood vessel that carries oxygen-rich blood from the lungs to the left side of the heart |
| Cordae Tendinea | tough, fibrous cords, often called "heart strings," that connect the heart's mitral and tricuspid valves to the papillary muscles |
| Papillary Muscles | a small, pillar-like muscle inside the heart's ventricles that helps control the flow of blood through the heart's valves |
| Septum | a dividing wall or membrane especially between bodily spaces or masses of soft tissue |
| Tricuspid Valve | a valve in the heart with three flaps that controls blood flow between the heart's two right chambers: the right atrium and the right ventricle |
| Bicuspid/Mitral Valve | a heart valve with two flaps that regulates blood flow from the heart's upper left chamber (left atrium) to the lower left chamber (left ventricle) |
| Aortic Semilunar Valve | connect your heart ventricles (lower chambers) and arteries |
| Pulmonary Semilunar Valve | a valve of the heart that lies between the right ventricle and the pulmonary artery, and has three cusps |
| Brachiocephalic Artery | a major blood vessel that branches off the aortic arch and supplies blood to the right arm, head, and neck. |
| Left Main Coronary Artery | a short artery that branches from the aorta to supply oxygen-rich blood to the left side of the heart |
| Left Anterior Descending Coronary Artery | a major blood vessel that supplies oxygen-rich blood to the front and left side of the heart muscle. |
| Circumflex Coronary Artery | a major blood vessel that branches from the left main coronary artery and curves around the left side and back of the heart. |
| Left Posterior Descending Coronary Artery | a major artery that branches off the left coronary artery and supplies blood to the front and left side of the heart |
| Right Coronary Artery | sends blood to the right side of the heart |
| Posterior DescendingCoronary Artery | supplies the posterior third of the interventricular septum and the inferior wall of the left ventricle |
