1. How does the Musculoskeletal System help the body maintain homeostasis?

The musculoskeletal system provides support for the body and protects its organs. The bones store minerals and make blood cells. The muscles, both inside and outside of the body, allows for necessary body movements. The heart is a muscle that allows blood to flow throughout the body and provide necessary materials that the body can use to stay alive. 

​

2. How does the circulatory and respiratory systems work together to allow the body to maintain homeostasis? The circulatory and respiratory systems work to allow blood to flow to the lungs and receive oxygen that the body needs to survive. The blood carries nutrients to organs in the body and carries away wastes from the organs so they can eventually be expelled from the body.

​

3. How does the digestive and excretory systems work together to help the body maintain homeostasis? The digestive and excretory systems work together to convert food into energy that the body needs to carry out its functions. The systems work to carry away and release waste products that organs do not need and can be harmful if not expelled.

4. How does the nervous system work to help the body maintain homeostasis? The nervous system, which includes the brain, spinal cord and nerves, coordinates the body’s activities and helps it sense and respond to changes in the environment.

5. How does the reproductive system function? The reproductive system consists of male sex cells (sperm) and female sex cells (egg) that can join to produce offspring during fertilization
