Define Water as a medium and solvent?

Water is the medium of all cell fluids, including digestive juices, lymph, blood, urine, and perspiration. All the physiochemical reactions that occur in the cells of the body take place in the precisely regulated environment of the body fluids. Water enters into many essential reactions, such as hydrolysis, that occurs in digestion. Water is an end-product in the oxidation of energy-yielding nutrients. Water is a solvent for the products of digestion, holding them in solution and permitting them to pass through the absorbing walls of the intestinal tract into the blood stream. Due to its ability to dissolve the nutrients and cellular waste products, it carries nutrients to the cells and removes the waste products to the lungs, kidneys, gut and skin.
