This site is good because it explains the difference parts of the heart and explains how it works. It is able to use information and sue it in a way that young people can even understand. They also give lots of information that is useful. I learnt things about the heart and how it has lots of different parts to it. I also learnt that it isn't the heart that creates the blood, it only pumps the heart and distributes the blood around our body. I also learnt that there is in the circulatory system, the heart is the key part of it.
