Which organ system is most responsible for maintaining control of body temperature?
The circulatory system carries blood throughout the body, and plays an important role in controlling body temperature. Capillaries below the skin contract or expand to release or contain body heat. Heat is also transported from hotter parts to colder parts to ensure an even body temperature. The skeletal system protects organs and provides the body with its structure and shape. The immune system helps fight off illnesses and infections. The muscular system is what allows the body to move.
