How does gastrointestinal tract evade dehydration? 1) Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system 2) water is an important digestive enzyme in the stomach. 3) Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system. 4) the water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach.
