1. Well the nervous system, for starters, gives instructions via electrical pulses to every nerve etc as to what to do and so forth, it's basically the "power house." It tells all the organs to do what they do. The digestive system breaks down nutrients which enter into the bloodstream, thus involving the circulatory system. The circulatory system pumps blood into the lungs and the lungs pump oxygen into the blood, thus connecting the circulatory and respiratory systems. The skeletal system protects all these organs and organ systems, and the muscles are responsible for much of the action in the organs, as well as being connected to the bones of the body for mobility. The skin covers it all in one package.
2. Just think about it. The circulatory system helps the nervous system by supplying blood to the brain. It helps the respiratory system by oxygenating blood. The endocrine and reproductive systems work together. Circulatory also helps the digestive system, need blood to make the intestines work.
