to cancel out the difference to bring it back to its normal. An example of this is if blood glucose level falls the body will then convert the glycogen in the body to glucose which will bring back the energy in the cells to its normal amount. This system requires receptors so that they are able to detect the change in your body. As well as receptors it also needs a control centre so that the information that has just been received can be processed to then give the correct response of what the body

The first step should be to consider that using an experiment

The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral tissue to the brain. The ANS consists of three components: the sympathetic‚ noradrenergic and parasympathetic‚ cholinergic systems that occur in the CNS‚ with the cell body in the brainstem and spinal cord and ENS 68.

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their
