n Body Systems 6. How does the digestive system interact with the circulatory system? OA. Nutrients and gases are absorbed by organs in the circulatory system. Then, they are transported to all parts of the body by organs in the digestive system. OB. Oxygen and carbon dioxide are exchanged by organs in the digestive system, and the gases are carried to the rest of the body by the circulatory system. OC. Nutrients taken in and broken down by the digestive system are carried to various parts of the body by the circulatory system. OD. Messages sent as electrical impulses from the digestive system are transported throughout the body by the circulatory system. Reset Submit Session Score: 80% (4/5) 5 of 10 Answered

9.How does gastrointestinal tract evade dehydration? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. Water is an important digestive enzyme in the stomach. Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system The water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach. Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system.
