| Question | Answer |
| These stop the back flow of blood around the body. | Valves |
| Name the 2 types of chambers in the heart. | Ventricles (Left and Right) Atria (Left and Right) |
| This is the main artery in the body; reaching from the heart to the abdomen. | Aorta |
| Name the 2 types of blood which is in the heart. | Oxygenated and Deoxygenated |
| What type of muscle is the heart? | A Cardiac muscle |
| What does the heart help with, in terms of living? | Respiration |
| What is the balanced equation for respiration? | C6H12O6 + 6O2 → 6CO2 + 6H2O |
| What is the name of the thick muscle wall which runs down the centre of the heart? | The Septum |
| Why is the muscle thicker on the L than on the R? | The left side holds the oxygenated blood and therefore each pump has to carry the blood around the whole body. |
| This is found between the artia and the ventricles. It stops back flow into the atria, and it is made of strong fibres to stop it turning inside out. | Atrioventricular Valve (AV) |
| This prevents back flow into the ventricle from the aorta and the pulmonary artery. | Semilunar Valve |
| This carries deoxygenated blood from the heart to the lungs. | Pulmonary Artery |
| These are large blood vessels that receive oxygenated blood from the lungs and drain into the left atrium of the heart. | Pulmonary Vein |
