The endocrine system only regulates long-term changes in the body

This statement is not entirely accurate. While the endocrine system does play a significant role in regulating long-term changes in the body, such as growth, development, and metabolism, it also has a role in short-term responses to stress, injury, and other environmental changes.

Hormones released by endocrine glands can act quickly in response to a stimulus, such as the release of adrenaline in response to a threat or the regulation of blood sugar levels after a meal. These short-term responses help the body maintain homeostasis and respond to its immediate needs.

Overall, the endocrine system contributes to both short-term and long-term regulation of the body's internal environment and plays a crucial role in maintaining overall health and function.
