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
