What system is composed of specialized glands that affect growth and development?

Nervous system
Circulatory system
Endocrine system
Immune system

The correct answer is: Endocrine system

The correct choice is the endocrine system because it is specifically responsible for producing and regulating hormones that influence growth, development, metabolism, and overall bodily functions. Hormones are chemical messengers that are secreted by various glands in the body and travel through the bloodstream to target organs, where they exert significant effects on physiological processes. This regulation and control over bodily functions make the endocrine system crucial for maintaining homeostasis and facilitating normal development throughout different life stages. In contrast, the other systems mentioned do not primarily focus on growth and development. The nervous system primarily handles rapid communication between different parts of the body through electrical signals, while the circulatory system is responsible for transporting blood, nutrients, gases, and waste products throughout the body. The immune system is involved in protecting the body against pathogens and diseases but does not directly influence growth and development in the same manner as the endocrine system does.
