The water from the undigested food is absorbed in the large intestine. The big intestine is the lowermost section of the digestive system or gastrointestinal tract. Food digestion and absorption depend heavily on our digestive tract. The small intestine can absorb water and nutrients to 90%. Most of the electrolytes and fluids from the digested food are absorbed by the large intestine.

Where is Water from the Undigested Food Absorbed?

In vertebrates, the large intestine is the last organ of the digestive system. In this step, water is absorbed, and the leftover waste is stored as feces until being eliminated by egestion or defecation. The big intestine is quite thick and around 5 feet long. It has microorganisms that break down the trash and small amounts of nutrient accumulation while soaking up water.

The large intestine is where most of the water from unprocessed food is absorbed. Before food may enter the large intestine, it must travel through the digestive system for several hours. Goblet cells in the large intestine utilize the water in the meal residue to stay hydrated.

Water from Undigested Food

The digestive system breaks down food into smaller forms so that they may be rapidly and easily taken up by our blood vessels and absorbed into circulation since the food we consume is complex and cannot be absorbed straight into the blood.

  • Because it can absorb most of the water from undigested food, the large intestine plays a significant role in our digestive system.
  • Before reaching the rectum, the material passes through the colon’s ascending, transverse, descending, and sigmoid portions. Through the rectum, waste is expelled from the body.
  • The large intestine is approximately five feet long (or 1.5 meters).
  • The big intestine is far broader and passes through the belly much more directly than the small intestine.


Water from the Undigested Food is Absorbed Mainly in the

The large intestine absorbs the water from the undigested meal. The digestive system is the gastrointestinal tract’s lowermost portion, known as the big intestine. Our digestive system plays a major role in how food is absorbed and digested. The large intestine is responsible for absorbing the majority of the electrolytes and fluids from the digested food. Peristalsis, mass peristalsis, and haustral churning are the main forms of movement in the large intestine.
