Answer 2

Answer:

Explanation:

The body's communication systems are the endocrine and nervous systems. At an integrative level, the primary function of the nervous system is to control many of the functions of our bodies and minds. It does this by extracting information from the environment using sensory receptors, sending signals that encode this information into the central nervous system, processing the information to determine an appropriate response, and sending output signals to muscles or glands to initiate the response. The nervous system responds rapidly to short-term changes. By nature, these hormones are synthesized at a distance from their target cells and travel through the bloodstream or intercellular fluid until they reach these cells. Upon reaching their target cell, the hormone acts on the cell to increase or decrease the expression of specific genes. This process takes significantly longer than that of the nervous system, as endocrine hormones must first be synthesized, transported to their target cell, and enter or signal the cell. Then, the target cell must go through the process of transcription, translation, and protein synthesis before the intended action of the hormone can be seen .
