How It Works

Body systems work together to help living things survive. When the skin is removed, the chicken's body systems can be more closely observed. For example, the bicep is part of the muscular system. The thin white lines in the muscles are called nerves, and they tell the muscles when to contract. Nerves are a part of the nervous system. The blood vessels deliver nutrients to the muscle and remove waste. They are part of the circulatory system. When cutting the bicep muscle, you can see the bones it is connected to, which are part of the skeletal system. They give living things structure and places for muscles to attach. If one of these systems stopped working, the chicken wouldn’t be able to survive.
