The Nervous System:

Function:

     The function of the Nervous System is to help you control everything you do and control things you cannot control yourself such as your heart.

Organs:

     The organs that make the Nervous System is the brain which controls every part of your body, the spinal cord acts as a way for your brain to communicate to the rest of your body, and the nerve cells which are the cells that send messages to and from your brain and your body and makes up the spinal cord.

Interactions w/ Other Systems:

     The Nervous System works with almost everything in your body. It works with the Muscular System by making the muscles and body move. The Nervous System also controls the heart pumping in the Circulatory System, and works with the Digestive System and moves muscles to help you digest food you eat. The Spinal Cord, which is part of the Nervous system is protected by the spine- part of the Skeletal System. It also helps the body feel and sense when something is touching the body.

Analogy:

Explanation:

     The analogy that I chose for this system is a CPU. The function of a CPU is to send instructions to the computer and do simple thinking and math. The Nervous System does the same thing. This system's function is to do all the thinking that the body needs to do and send instructions to the rest of the body to do basic things such as moving. This is why I compared a CPU to the Nervous System

Structure and Function:

     The part of this system that I chose for this section was the brain. When looking at the brain, it seems like it is folded instead of being smooth. I think that the brain is shaped this way because it does something similar to the small intestine in the digestive system. The small intestine is folded down because when stretched out, it is about 20 feet. So it the small intestine is folded to fit inside the body. I think the same thing goes with the brain. The brain is folded in to pieces because it must be big, which makes sense since the brain is responsible for almost if not all actions in your body. The brain is folded so it could fit inside the skull.
