• B.

Large intestine, stomach, esophagus

• C.

Mouth, stomach, esophagus

• D.

Stomach, small intestine, esophagus

A. Esophagus, stomach, small intestine
Explanation
The correct answer is "Esophagus, stomach, small intestine". This is because the food first enters the esophagus, which is a muscular tube connecting the mouth to the stomach. From the esophagus, the food then moves into the stomach, where it is broken down further by stomach acids and enzymes. Finally, the partially digested food passes into the small intestine, where the majority of nutrient absorption takes place.

### Which part of the small intestine increases the surface area for absorption?

• A.

Cappillaries

• B.

Duodenum

• C.

Lacteals

• D.

Villi

D. Villi
Explanation
The villi are finger-like projections that line the inner surface of the small intestine. They greatly increase the surface area available for absorption of nutrients. The increased surface area allows for more efficient absorption of nutrients into the bloodstream. Capillaries and lacteals are both involved in the absorption process, but they do not specifically increase the surface area like the villi do. The duodenum is the first part of the small intestine, but it does not directly contribute to increasing the surface area for absorption.
