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.
What else can I help you with?
Why do tapeworms need a digestive system?
Tapeworms do not have a digestive system because they absorb nutrients directly through their skin from the host's intestines. They rely on their host's digestive system to break down food, which the tapeworm then absorbs.
Why does the digestive system separate the nutrients?
To break them down and properly absorb them.
What are the digestive system functions?
I'm pretty sure its to absorb nutrients and eliminate waste
Why do human should have digestive system?
To absorb different nutrients, and to filter what we eat and drink
Why do you think flatworms do not have a digestive system?
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.
Why do you think parasitic flatworms do not have digestive system?

Why is it necessary that blood is pumped to the digestive system?
Blood has to be pumped to the digestive system so that carbon dioxide can be extracted from it. The blood can also absorb nutrients that have just been collected from the digestive system.
Organ system that breaks down food and absorb nutrients?
The digestive system is responsible for breaking down food into smaller molecules that can be absorbed by the body. This process occurs in the stomach and intestines, where nutrients are absorbed into the bloodstream for use by the body.
Can humans absorb nutrients from the air?
No, humans cannot absorb nutrients from the air. Nutrients are primarily obtained through the food and beverages we consume, which are broken down in the digestive system for absorption into the body.
What is the organ in the digestive system that releases nutrients into the bloodstream by the process of absorption?
The small intestine. It has villi that absorb nutrients and then transport them to the bloodstream.
Can the tongue absorb nutrients?
Yes, the tongue can absorb some nutrients such as certain medications and vitamins. However, it is not a major site for nutrient absorption compared to the digestive system in the gut.
Why dont most parasitic flatworms need a complex digestive system?
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.
