What two substances would be gained by blood as it passes through the small intestine?

The two substances that would be gained by blood as it passes through the small intestine are water and nutrients. The small intestine is the main organ responsible for the absorption of nutrients from food. It is a long, coiled tube that is lined with villi, which are small finger-like projections that increase the surface area of the intestine and help to absorb nutrients. The blood vessels in the villi absorb water and nutrients from the food and transport them to the rest of the body.
