Nancy is having difficulty digesting fatty foods. After seeing her doctor, who found no evidence of inflammation, she says that she must now see a specialist to determine why she is having trouble releasing bile from her gallbladder. What hormone is most likely functioning improperly for Nancy?

Answer: Cholecystokinin

Explanation:

Cholecystokinin is the hormone which is secreted by the cells of the small intestine. The secretion is stimulated under the infleunce of amino acids, hydrochloric acids, and fatty acids into stomach or duedenum. It stimulates the gallbladder to release the stored bile into the intestine to facilitate digestion of fatty foods.

According to the given condition, cholecystokinin is the hormone which is not functioning properly.

The cholecystokinin hormone is the one responsible for releasing the bile from gallbladder.

Explanation:

The cholecystokinin hormone is produced from cells in the duodenum (a part of the small intestine). When we eat food rich in fats, this enzyme stimulates the contraction of gallbladder to release the bile. Additionally, this enzyme stimulates other areas of the gastrointestinal system (pancreas and liver) to digest fat, proteins and carbohydrates and also is responsible for reducing appetite while we are eating. The persons who have little cholecystokinin have problems in digesting fats and also is related to obese people.
