Explain why it is important for nervous and hormonal mechanisms to control the secretion of digestive juices.

Two main reasons contribute to the significance of control secretion of digestive juices. The first is that, given the natural gaps between an animal’s meal and the next, gastric juices aren’t actively secreted all the time. Otherwise, it would not be possible to conserve energy between meals. Secondly, when an animal’s fight or flight response is activated, they need energy from the digestive process to invest in muscle use.
