How does the digestive system absorb nutrients?

Answer 1

Well to understand how our bodies are capable of digesting plants we must familiarize ourselves with some of the major organs that are responsible for providing the proper enzymes. One of the most commonly misunderstood factors is that the stomach cannot digest the cellulose in plants. However, this should not be misinterpret as not being able to digest vegetables.

First the saliva glands releases enzymes that bind to the food as it goes down the esophagus. Then in the stomach lining, other enzymes called stomach acids are released to break down proteins. However, since plants have a very strong cell wall, the enzymes can barely take anything off the external layer but can only separate each cell from binding which allows them to pass into the pancreas which produces a juice that further shrink the cellulose, although it does not destroy them but only shrinks them further to have them absorbed into the the blood stream. Those that did not get separated go out in waste. In the blood stream, the cellulose stays intact while scraping off unwanted cholesterol as it travels. At this point, the plant cells have become much weaker than when they were in the stomach and are all flowing independently. Finally, the cholesterol and the plant cells go through the liver where they are destroyed by the liver's enzyme called the biles. Biles are enzymes that are far more powerful than the stomach acids and they dissolve even cellulose.

Answer 2

The length of the intestines creates more surface area for food to be broken down upon; the villi contain capillaries for the nutrients to be moved through to the blood; carrier molecules assist in transporting materials like amino acids and simple sugars across the membrane.

Answer 3

yes of course our body had a strong enzyme to be able to digest the vegetebles in our body
