b) All the other 5 major systems help the respiratory system work at its best. The systems include the digestive system, skeletal system, circulatory system, muscular system, and finally the nervous system. The digestive system breaks down food into simpler substances that the body can use including proteins. This helps the respiratory system because the lungs need nutrients. The respiratory system helps the digestive system by giving oxygen to the digestive system. The skeletal system is like a metal shield covering the body. This system helps the respiratory system by protecting the lungs. The circulatory system transports the food nutrients, and oxygen to the body cells. It also delivers of carbon dioxide and waste products. This helps the respiratory system by transporting nutrients to keep the lungs clean, and healthy.
