This book will be talking about two body systems. we will be comparing them to two buildings found in a city.

The function of the skeletal system is to provide the body with support and protection. The organs of the skeletal system are the bones and the joints. This can be compared to a building because a building cannot stay up and standing without walls as a human cant without bones or joints.

The function of the muscular system is for the movement for the human body. The organs are the cardiac (heart) the smooth (stomach) and the skeletal (arms,legs,etc). THese can all be compared to a building in a city because without people working in the building and keeping it up and standing it would most likely end up falling in some years.

When someone is diagnosed with muscular dystrophy, the bones get weak and lose muscle mass. This would be similar to two buildings in a city when there are less people working in the city and the buildings work is less and less everyday until they go out of business and is broken down.
