What is the main function of the endocrine system?

To digest food
To protect the body
To regulate hormones
To provide oxygen

The correct answer is: To regulate hormones

The endocrine system is a collection of glands that produce and secrete hormones to regulate various functions in the body, such as metabolism, growth and development, and reproduction. It is responsible for maintaining homeostasis in the body by regulating the levels of hormones in the bloodstream. Option A (to digest food) is incorrect because that is the main function of the digestive system. Option B (to protect the body) is incorrect because that is the main function of the immune system. Option D (to provide oxygen) is incorrect because that is the main function of the respiratory system. Therefore, the main function of the endocrine system is to regulate hormones.
