Question

Which of the following functions of the digestive tract and accessory organs involves the progressive dehydration of indigestible materials and organic wastes prior to elimination from the body?
A. Ingestion
B. Mastication
C. Compaction
D. Defaction

Answer 1

Answer:

C. Compaction

Explanation:

Chyme enters from the small intestine into the large intestine. In the large intestine, chyme becomes solid or semisolid as the water is absorbed from it. Absorption of excess water from chyme to convert it into the feces in the large intestine is called compaction. Feces consist of water, inorganic salts, unabsorbed digested materials, and indigestible parts of food.  During compaction, enough water is absorbed and this makes large intestine one of the important organs in maintaining the body’s water balance.
