HUMAN NUTRITION

Detailed explanation-1: -The ileum is the last and longest section of the small intestine. Here the walls of the small intestine begin to thin and narrow, and blood supply is reduced. Food spends the most time in the ileum, where the most water and nutrients are absorbed.

Detailed explanation-2: -The ileum is the final portion of the small intestine, measuring around 3 meters, and ends at the cecum. It absorbs any final nutrients, with major absorptive products being vitamin B12 and bile acids.

Detailed explanation-3: -Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-4: -Absorption. The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.

Detailed explanation-5: -In the small intestine the food (proteins, fats and carbohydrates) is hydrolyzed by hydrolytic enzymes and absorbed through the large surface area of the ileum and jejunum. In the large intestine the residual food components that have not already been digested are fermented by microorganisms.
