Elderly male patient with stomach cancer had a feeding tube inserted into his alimentary
canal to bypass esophagus, stomach, and duodenum. He had his gallbladder removed years ago.
-
What is not able to occur in his
digestive system. Indicate how this will impact the food he can be given?
The food will not be able to be broken down into a bolus because of the lack of mucus from his esophagus. It will also not be able to be broken down into chyme, which will prevent the small intestine from properly absorbing the food.
The food that needs to be given to the patient must be diluted enough and broken down enough for the small intestine to be able to absorb the nutrients.

Small intestine
Receives chyme from stomach and where chemical digestion of macromolecules + absorption of nutrients, water, and electrolytes occur.
Large intestine
Absorbs water, electrolytes, and vitamins.
