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 will have problems making glycogen, which is mobilized and converted to glucose by gluconeogenesis when the blood glucose concentration is low. Glucose may also
