Final answer:
The incorrect statement about the digestive system in older adults is that emptying of the esophagus and stomach becomes faster and there is an increase in digestive enzymes. In reality, aging typically slows down the digestive process and reduces enzyme secretion.
Step-by-step explanation:
Direct answer in 2 lines: The statement that is NOT true about the digestive system is 'B) As people move into older adulthood, emptying of the esophagus and stomach becomes faster and there is an increase of digestive enzymes.'
Explanation in 200 words: As individuals age, many aspects of the digestive system undergo changes, but the emptying of the esophagus and stomach generally does not become faster nor is there an increase in digestive enzymes. In fact, the aging process often results in a slower movement of food through the alimentary canal due to reduced strength and tone of the muscular tissue. This slows down the process of digestion and may lead to issues such as constipation and a decrease in the efficiency of nutrient absorption. Additionally, neurosensory feedback, which helps stimulate the release of digestive enzymes, also diminishes with age. This leads to a decreased secretion of digestive enzymes, contrary to what the incorrect statement suggests. Furthermore, older adults often experience a decrease in the thirst sensation, which can result in lower fluid intake and contribute to digestive issues. Common age-related problems include a decrease in appetite, difficulties in chewing due to a loss of teeth, and a general decrease in the efficiency of the digestive system.
