the endocrine system only regulates short-term changes in the body

Answer 1

This statement is not entirely accurate.

The endocrine system is responsible for regulating numerous physiological processes in the body, including metabolism, growth and development, stress response, and maintaining the body's internal balance or homeostasis. While some of the effects of the endocrine system may be short-term, such as the fight or flight response to stress, many of its regulatory functions are ongoing and long-term, such as growth hormone production, metabolism regulation, and reproductive hormone cycles.

In summary, the endocrine system plays a crucial role in both short-term and long-term changes in the body.
