1. The most surprising thing about the heart dissection would be the colour changing, but since I already have done a heart dissection before it wasn't as surprising. From last time I didnt remember what the chordae tendiane was until I saw it in the heart I felt how stretchy it was.
2. Atria and the ventricles are different because the ventricles are bigger compared to the atria plus the function of the atria is to collect blood and pass it to the ventricle.
3. The left ventricle is more muscular than the right because the right ventricle only has the job to carry deoxygenated blood to the lungs and back.
4. The function of the heart valves are that it keeps the blood following and it sends blood to the proper place.
5. Pictures aren't uploading.
