nervous system
Function: The nervous system controls sight, hearing, taste, smell, and feeling (sensation).
It also controls voluntary and involuntary functions, such as movement, balance, and coordination. The nervous system also regulates the actions of most other body systems, such as blood flow and blood pressure.As well as the ability to think and reason. The nervous system allows you to be conscious and have thoughts, memories, and language.
Organs: The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. The brain is one of the most important organs in the body. It's where information is processed and responses originate. The brain, also controls higher mental functions such as consciousness, memory, planning, and voluntary actions, also controls lower body functions such as the maintenance of respiration, heart rate, blood pressure, and digestion. The function of the spinal cord is to send off nerve signals to the body from the brain. Nerves act as information highways to carry signals between the brain and spinal cord and the rest of the body. The sense organs — eyes, ears, tongue, skin, and nose — help to protect the body. The human sense organs contain receptors that relay information to the appropriate places within the nervous system.
Analogy: 
My analogy is an email being sent from one place to the other. This is similar to the nervous system because information is being sent from one place to another, such as when the brain sends information and it travels to the arms so they move. Such as when someone sends an email and it travels and a person reads it.
Structure and Function: The spinal cord. The spinal cord connects from the brain all the way down to the hips so that when the brain gives messages it travels from the brain down the spinal cord, to the nerves so your body does it. It's shape relates to it's function because first it has a long pole down so you have some support from that organ but also it has things coming out from it so it can send messages to the part of the body depending on the part it's on. Depending on the spots on the spinal cord different messages are sent. Also the spinal cord is mostly nerves, this is so it can send messages quickly with all of the nerves, as well as it has a variety of nerves that do control different functions because it has to control many different functions.
