| Question | Answer |
|---|---|
| Vein | Carries blood from body back to heart. |
| Aorta | Largest artery in the body. |
| Capillary | Smallest blood vessels. |
| Septum | Divides the heart into right and left halves. |
| Left Atrium | Receives oxygenated blood which is returned from the lungs |
| Endocardium | Inner layer of heart. |
| Tricuspid Valve | Located between right atrium and right ventricle. |
| Sinoatrial (SA) Node | Natural pacemaker of the heart. |
| Pulmonary Circulation, pathway of blood. Where does the blood from the body go? | Right Atrium |
| Pulmonary Circulation, pathway of blood. From the right atrium where does the blood go? | Through the tricuspid valve into the right ventricle. |
| Pulmonary Circulation, pathway of blood. From the right ventricle where does the blood go? | Through the pulmonary semilunar valve into the pulmonary artery. |
| Pulmonary Circulation, pathway of blood. Where does the pulmonary artery take the blood? | Into the lungs to be oxygenated, and give up carbon dioxide as well as waste. |
| Pulmonary Circulation, pathway of blood. After the lungs where does the blood go? | To left atrium of the heart via the pulmonary vein. |
| Systemic Circulation, pathway of blood. From the lungs where does the blood go? | To the left atrium. |
| Systemic Circulation, pathway of blood. From the left atrium, where does blood go? | Through the mitral valve into the left ventricle. |
| Systemic Circulation, pathway of blood. From the left ventricle, where does blood go? | Through the aortic semilunar valve into the aorta. |
| Systemic Circulation, pathway of blood. From the aorta where does blood go? | Through the body into smaller and smaller arteries. |
| Systemic Circulation, pathway of blood. In the capillaries, what happens? | Blood and oxygen from the arteries is exchanged with carbon dioxide from cells, which now flo in the veins. |
| Systemec Circulation, pathway of blood. From the body, what brings the blood to the heart? | Veins |
