One’s lifestyle can affect both systems. If you live a healthy lifestyle, your respiratory and circulatory system will be healthy too. The oxygen can be delivered all throughout the body. But, when you live an unhealthy lifestyle (ex. Smoking), there is a possibility that the whole circulatory or respiratory system will be damaged and can cause death to the person.
