Feature Structure Function Atria (singular atrium) thin walled no valves rough pectinate muscles sinus node (impulse generating tissue) interatrial septum Right atrium: Receives deoxygenated blood returning to the heart from the vena cava and pumps it to the right ventricle. Left atrium: Receives oxygenated blood returning to the heart from the pulmonary veins and pumps it to the left ventricle. Ventricles thicker walls (than atria)‚ the left is thicker than the right as blood must be pumped all

How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve.

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat
