|These stop the back flow of blood around the body.
|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.
|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?
|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?
|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.
|This carries deoxygenated blood from the heart to the lungs.
|These are large blood vessels that receive oxygenated blood from the lungs and drain into the left atrium of the heart.
