The Human Body
The humanbody is like a complex organization that has an important job to get done on a
tight deadline. In order to get everything done perfectly and on time, it has to use a
system. Actually, the human body uses many systms that work side by side. Some of the
body's systems are directly connected to the heart, while others are not. Of cousre, the
heart is like the president of the organization. Even if it is not directly involved in the
system, it still play a part. Obviously, if the heart aren’t working, nothing else is working
either.
