Integumentary System (Skin)The integumentary system 

has many functions. One of the main functions is keeping you cool by sweating. Sweat is excreted water. In the water can be salts and organic compounds. The sweat and other materials are released through sweat glands in your skin.

Digestive SystemOnce it is done processing your food, the digestive system excretes the leftover materials. This includes solid waste and water. The large intestine moves the solids into the rectum. They are released through the anus along with any unabsorbed water.

Respiratory SystemThe respiratory systems is responsible for exchanging oxygen and carbon dioxide. This exchange takes place in the lungs. The carbon dioxide is released every time you exhale. If you have ever breathed on a mirror and fogged it up then you know that water is also released every time to breath out.
