What system regulates the body's hormones?

1. Nervous system

2. Musculoskeletal system

3. Endocrine system

4. Digestive system

The correct answer is: Endocrine system

The endocrine system is responsible for regulating the body’s hormones, playing a crucial role in maintaining homeostasis and coordinating other physiological processes. It consists of various glands, such as the pituitary, thyroid, adrenal glands, and pancreas, which secrete hormones directly into the bloodstream. These hormones influence metabolism, growth and development, tissue function, and mood, among other vital functions. In contrast, the nervous system primarily facilitates rapid responses to stimuli through signaling via neurons, while the musculoskeletal system supports movement and physical structure, and the digestive system manages the breakdown and absorption of nutrients. Each of these systems has distinct roles, but it is the endocrine system that specifically handles hormone regulation, making it the correct choice in this context.
