•Try and orientate the heart as it would lie in the chest •Try and decide which parts are the atria and which parts are the ventricles •Can you see any coronary arteries? •Try and lift up a piece of valve tissue with a pair of forceps. Can you see the strings attaching the valve to the ventricular muscle, are they strong or weak? •Pull on one and observe what happens to the valve tissue. •Cut through the heart in the direction of the yellow straw, right down the heart: you should have opened up the left ventricle, •Look at the thickness of the wall of the left ventricle. What do you notice? • You will have also cut through the mitral valve, have a look at the valve tissue and the tendinous chords that attach it to the ventricle. •Feel the walls of both atria. Is there a difference in thickness? Get 4 coloured straws orange - vena cava, green - pulmonary artery, pink - aorta yellow - pulmonary vein. •You should find that a pair of straws ends up in each side of the heart – look at the diagram on the board to see why •Cut along the heart in the direction of the orange straw, down to the bottom of the heart. • This should open up the rest of the right atrium and show you inside the right ventricle. Is there any difference in thickness between the right atrium and the right ventricle? • You will have cut right through the tricuspid valve too. Cut through the heart in the direction of the aorta (red straw ). You should be able to open up the aorta to see the semilunar valves. In the region of the semilunar valves try and find a small hole – this is the beginning of a coronary artery
