Zachary’s Story.

1. An ulcer starts by eroding the mucosa of the G.I tract wall. What functions of digestion or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis?

Absorption would not happen correctly because some of the ingested and secreted may seep out of the lumen. This could also create a pathway of entry for pathogens, if the ulcer ate its way through to the muscularis mucosa and lose some control of defecation.

Zachary can also digest triglycerides because the enzyme secreted by lingual glands in the tongue start to break down but does not activate until the bolus reaches the stomach.

Zachary will end up with extrahephatic jaundice due to the blockage of bile drainage and he will become malnourished and lose weight.
