In order to maintain homeostasis, the systems of the human body work together to keep a constant internal temperature. Which of the following best describes how the human body responds in a cold environment?

• The digestive system produces more hormones to warm the body.
• The nervous system signals the muscles of the muscular system to contract and warm the body.
• The circulatory system delivers less carbon dioxide to the muscular system, resulting in stiffening of the muscles.
• The skeletal system produces more blood cells that circulate through the blood vessels, increasing the warmth of the body.
