What is time required for human digestion?

Answer 1

After putting the 'food' into your mouth, it then has to travel through the entire gastrointestinal tract before coming out the other end. The gastrointestinal tract for the purposes of this exercise includes the oral cavity, the esophagus, stomach, small intestine, and colon.

Food travels down the esophagus at a rate of approximately 1 to 2 inches per second, and the entire process takes about 5 to 6 seconds. In the stomach, food tends to hang around for a little longer and this depends on a variety of factors including the amount of food you have consumed, how much fat it contains, and also the acidity of the stomach. However, all food should have left the stomach within 2 to 4 hours.

In the small intestine, digestion continues and absorption occurs. From here on, the time to defecation will vary depending on the time it takes to adequately digest and absorb in the small intestine. This will usually take 5 to 6 hours. The "food then enters the colon for further digestion and water re-absorption before defecation. The time from it's entering the colon to defecation is about 12 to 24 hours.

Thus, the time for food to travel from one end to the other probably ranges from about 20 to 30 hours.

Answer 2

Water isn't really digested - it soaks through the inside wall of your intestines and goes right into the bloodstream. Then the kidneys take out all extra water, if they can. I have had a large, large drink of water go through me in about a half hour.

So your answer is "No time, at all", because it doesn't digest.

Answer 3

Digestion is one of the most complex processes that the human body undergoes. The entire process can take from a few seconds to a few days. In the case of simple sugars, they are digested and absorbed in the mouth. As far as more complex carbohydrates, fats, and proteins, the process takes longer. Most of our protein digestion occurs in the stomach and can take up to 4-6 hours. The next part of digestion takes place in the small intestine, the duodenum. This is the only part of our system that can digest all three types of food, proteins, carbohydrates, and fats.

Answer 4

The time required for human digestion varies depending on the type of food consumed, but generally it takes 24 to 72 hours for food to pass through the entire digestive system. The stomach empties its contents into the small intestine within 2-4 hours after eating, where the majority of digestion and absorption takes place. Subsequently, the remaining indigestible material moves into the large intestine for further processing before being eliminated as waste.
