The most important part of the skeletal system is the skeleton.
Our bones make a lot of things possible.
Our bones help our muscles because without our bones muscles would be pointless.
The most important part of the circulatory system is the heart
The heart pumps out blood and gives that blood to the rest of our body
The heart connects to a lot of parts of the body, without it we would be dead.
