The respiratory system is the gas exchange of erythrocytes and the lungs, and erythrocytes and the rest of the body. The digestive system is the process of digestion. Respiratory: Involves gas exchange and lungs, plus the heart. Supplies the body with oxygen and gets rid of carbon dioxide. Includes ventilation (pulminary), internal and external gas exchange. You can get the idea, I hope. Digestive system: Is the process of absorbing nutrients you have eaten and excreting it through the colon. Involves enzymes. Involves the stomach, esophagus, mouth, small intestine, duodenum, liver, gall bladder, pancreas, colon, (pardon if I missed a few). Water gets reabsorbed in the colon.
Ice is a solid, water is a liquid, and oxygen is a gas in the air we breath.
