As food moves through the digestive tract, it spends the most time in the:

a) esophagus because of the slow movement of peristalsis on chewed food.
b) stomach because of the extensive breakdown of carbohydrates and fats.
c) small intestine because of the time it takes to absorb through the villi.
d) large intestine because of the need to partially digest fiber and absorb water.

Option B, Stomach because of the extensive breakdown of carbohydrates and fats.

Explanation:

Food is mechanically and chemically digested in the stomach by using enzymes, hydrochloric acid and peristalsis. Polymers of proteins, lipids and carbohydrates are broken down to simpler molecules such as amino acids and glucose for adequate absorption by microvilli in the small intestine.
