What is the function of folds and villi? a. allowing particles in the small intestines to flow from the jejunum to the ileum b. expanding volume to increase gas exchange from the respiratory system to the digestive system c. increasing surface area to improve nutrient absorption between the digestive and circulatory systems d. trapping food particles that flow through the small intestines

Correct C) Increasing surface area to improve nutrient absorption between the digestive and circulatory systems

The small intestine contains a large number of small finger-like projections called villi, which increases the intestinal surface area and help in the absorption of nutrient from the intestine.

These villi consist of numerous blood vessels, which absorb the food and transport it to the bloodstream.
