What is the cell body?
The long part of a nerve cell, it brings impulses away from the cell body.
The large part of a neuron, where the nucleus is located. It connects the dendrites and axon to each other.
What is the spinal cord?
Long bundles of neurons that run up your spinal column. It carries impulses from all parts of the body to the brain and from the brain to all parts of your body. Reflexes occur here.
Regulates the flow of information between the brain and the rest of the body.

Which of these is an example of the relationship between the nervous system and the circulatory system (the system that carries blood around your body)?
If a person's brain is not receiving enough blood, that means that the brain will start to send the wrong signals to the wrong part of the body, like making your stomach think it is hungry when actually you are not.
The brain produces wastes that red blood cells need to take away from the brain. If the blood does not do this, the brain can get poisoned.
If a person's brain is not receiving enough blood, that means their brain starts to "suffocate" because it is not getting enough oxygen. When the brain doesn't receive enough oxygen, the result is that the person will have a stroke.
