What is the small intestine mainly responsible for?

The jejunum and ileum lower in the intestine are mainly responsible for the absorption of nutrients into the bloodstream. Contents of the small intestine start out semi-solid and end in a liquid form after passing through the organ.

How is the small intestine designed to absorb digested food?

The small intestine has millions of tiny finger-like projections called villi. These villi increase the surface area for more efficient food absorption. Within these villi, many blood vessels are present that absorb the digested food and carry it to the bloodstream.

What features of the small intestine facilitate its role of digestion and absorption?

The small intestine is where digestion is completed and virtually all absorption occurs. These two activities are facilitated by structural adaptations that increase the mucosal surface area by 600-fold, including circular folds, villi, and microvilli.

Why do the stomach and small intestine have to dissolve the food you eat?

Food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.
