Final answer:
Naso-gastric tube feeding in a healthcare facility involves understanding the digestive system, including elimination, absorption, mastication, and peristalsis, all crucial for the feeding process. Mucus and chloride ions are also important elements in the digestive function relevant to feeding. Knowledge of the pharynx's role is also necessary for proper feeding procedures.
Step-by-step explanation:
When discussing naso-gastric tube feeding within a healthcare facility, it's important to address several statements regarding the digestive system. For instance, the digestive system's functions include elimination of waste, absorption of nutrients into the blood, mastication (chewing) of food, and peristalsis, which are waves of muscle contractions that move food through the digestive tract. In the context of a naso-gastric tube feeding, peristalsis is particularly significant as the tube relies on this muscular movement to help deliver nutrition directly to the stomach.
Furthermore, elements like mucus play a crucial role in the digestive system by protecting the lining of the gut and facilitating the movement of food. Regarding the chemical composition of gastric secretions, chloride ions are a true statement as they are a part of hydrochloric acid which aids in digestion. Lastly, discussing the pharynx, which is a region that food passes through on its way from the mouth to the esophagus, highlights the structural function of this part in the process of feeding.
