Intestine
Nutrients in the esophagus mainly pass through to the stomach via peristalsis, which is the coordinated muscle contractions that push food downward. Absorption of nutrients does not occur in the esophagus.
Digestion is the process of breaking down food into smaller molecules so they can be absorbed by the body. This typically involves mechanical digestion (chewing) and chemical digestion (enzymes breaking down nutrients). Absorption occurs in the small intestine, where nutrients are absorbed into the bloodstream for distribution to cells throughout the body.
Food is digested in the stomach, and this digestion continues to some degree in the small intestine. But it is largely in the small intestine that the nutrients are absorbed from the stream of digested materials. Anything not absorbed continues on to the large intestine for water extraction and further on to excrement.
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.
First of all, this is not an opinion question. It is purely factual. Most digestion takes place in the small intestine because that is where nutrients are absorbed and some of the food is broken down by chemicals (although some of that happens in the stomach, as well). The large intestine only absorbs water.
Well...It goes down the toilet.
When fresh fruit is liquidized, the cell structure is broken down, releasing the juices and nutrients within the cells. This results in a smoother consistency and easier digestion compared to eating the whole fruit. The process of liquidizing also makes the nutrients more readily available for absorption by the body.
digestion happens in these
Absorption of nutrients primarily occurs in the small intestine, specifically in the villi. The villi are finger-like projections that line the walls of the small intestine and help increase the surface area for absorption. Nutrients are absorbed into the bloodstream through the villi to be distributed throughout the body.
Some absorption also happens there however, most of the absorption of nutrients happens in the small intestines with the help of the many enzymes to break down the food that is digested by the stomach.
The human body needs a long digestive tract because digestion happens in several stages for different nutrients, it can't all be done in the same place. And the only way to fit such a long digestive tract in the human torso is by curling it up.
