Which two body systems are responsible for controlling the growth of bones?

• A. Skeletal and Immune
• B. Digestive and Nervous
• C. Skeletal and Endocrine
• D. Circulatory and Lymphatic

Answer: (C)

The skeletal and endocrine systems work together to regulate bone growth through a process that involves hormones produced by the endocrine system. Growth hormone, thyroid hormones, and sex hormones, such as estrogen and testosterone, play significant roles in stimulating bone development and regulating the balance of bone formation and resorption. The skeletal system serves as the framework that provides structure and support for the body, while the endocrine system releases hormones that directly influence the processes of bone growth and remodeling. For instance, before puberty, growth hormone and thyroid hormones help increase the length and mass of bones. After puberty, sex hormones have a crucial role because they accelerate growth and contribute to the closure of growth plates, ultimately determining the final height of an individual. The other systems mentioned do not have the primary role in bone growth regulation. The immune system primarily protects against disease, the digestive system focuses on nutrient absorption and metabolism, and the circulatory and lymphatic systems are more involved in transport and immune response than in the direct control of bone growth. Therefore, the correct pairing of the skeletal and endocrine systems highlights how growth is intricately regulated by hormonal signals.
