Question

Every cell in the human body needs a continuous supply of many specific nutrients for maintenance and physiological function. These nutrients are derived from the foods that we eat. Before the body is able to utilise nutrients for cellular function, foods much be broken down mechanically and chemically. The activities of the digestive system are finely coordinated and are integrated with the nervous, endocrine and circulatory systems. Select all of the TRUE statements that reflect the complexity and intricacy of the digestive process. The upper oesophageal sphincter opens in response to swallowing. At the bottom of the oesophagus, the lower oesophageal sphincter prevents reflux of the stomach contents. The acidic pH environment of the small intestine is well suited to pancreatic enzyme action. The structural organs of the GI tract have their own acid-base environments that allow for specific enzymes to become active and then inactive. Alterations in the pH environment of the small intestine would cause nutrient malabsorption. Dietary fibre is only important in maintaining stool consistency and regular bowel motions. To remove the nutrient molecules rapidly and provide room for more to be absorbed, a rush of circulating blood and lymphatic vessels continuously washes the underside of this surface of the intestinal cells, carrying the absorbed nutrients away to the liver and other parts of the body. The functions of the GI tract are an example of the body's ability to maintain homeostasis. The process of food digestion begins at the mouth and proceeds all the way through the to the large intestine. The secretions of digestion enter the GI tract at various points throughout the digestive process without the requirement for water.
