your digestive system has three main functions:digestion, absorption and elimination. in which organ dose absorption begin?
a. mouth
b.stomach
c.(small intestine)
d.gallbladder
Small intestine is the answer. You may want to review this subject.
The correct answer is c. (small intestine).
To arrive at this answer, let's break down each of the options:
a. The mouth is responsible for the initial stage of digestion, where food is chewed and mixed with saliva. However, absorption of nutrients does not begin in the mouth.
b. The stomach further digests the food through the release of enzymes and acids. While some limited absorption of water, alcohol, and certain drugs can occur in the stomach, the majority of the absorption happens in another organ.
c. The small intestine is the primary site of absorption in the digestive system. It is made up of three sections: the duodenum, jejunum, and ileum. The inner lining of the small intestine contains millions of tiny finger-like projections called villi. These villi increase the surface area and help facilitate the absorption of nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals.
d. The gallbladder is not directly involved in absorption. Instead, its function is to store and concentrate bile produced by the liver before releasing it into the small intestine to aid in digestion of fats.
Therefore, to answer the question, absorption begins in the small intestine (option c).
