Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.We breathe oxygen from the air into our lungs, and we breathe out carbon dioxide, which is formed in our body as a waste gas. Breathing is essential to life itself. Oxygen must pass from our lungs into our blood for our tissues and organs to work properly. We require Oxygen to live.
