This is true. The nervous system produces chemicals that affect our body at a rapid pace and the effects are usually short term and are designed for situations that are out of the ordinary. The endocrine system works slower and in the long run and there's not that much rapid effect that happens in stressful situations that the endocrine system solves or resolves. The hormones produced by the endocrine system are a constant that keeps being produced and they balance our body functions.
