What does the jejunum do in the digestive system?
The primary function of the jejunum is to absorb sugars, amino acids, and fatty acids. Both the jejunum and ileum are peritoneal. The ileum absorbs any remaining nutrients that did not get absorbed by the duodenum or jejunum, in particular vitamin B12, as well as bile acids that will go on to be recycled.
Does digestion occur in the jejunum?
The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins. The lowest part of your small intestine is the ileum. This is where the final parts of digestive absorption take place. The ileum absorbs bile acids, fluid, and vitamin B-12.
What type of digestion occurs in the jejunum?
Digestion and absorption The duodenum accomplishes a good deal of chemical digestion, as well as a small amount of nutrient absorption (see part 3); the main function of the jejunum and ileum is to finish chemical digestion (enzymatic cleavage of nutrients) and absorb these nutrients along with water and vitamins.
