Both digestion and absorption happen in which of the following parts of the digestive system?
Gallbladder
Esophagus
Stomach
Small intestine
The Correct Answer is D
Both digestion and absorption happen in the small intestine. Digestion is the process by which food is broken down into small molecules that the body can absorb and use for energy, growth, and repair. The final products of digestion are absorbed from the digestive tract, primarily in the small intestine.
The other options are not correct because they do not accurately describe where both digestion and absorption happen in the digestive system. The gallbladder stores bile produced by the liver, but does not play a direct role in digestion or absorption. The esophagus transports food from the mouth to the stomach, but does not play a direct role in digestion or absorption. The stomach plays a role in digestion by churning food and mixing it with gastric juices, but most absorption occurs in the small intestine.
