What happens to nutrients during the process of digestion absorption and excretion?
During digestion, food is broken down into its essential nutrients—carbohydrates, proteins, fats, vitamins, and minerals—primarily in the stomach and small intestine. These nutrients are then absorbed into the bloodstream through the intestinal walls. Any undigested food and waste products are eventually moved into the large intestine, where water is reabsorbed, and the remaining material is formed into feces for excretion. This process ensures that the body retains necessary nutrients while eliminating waste.

Absorption happens when nutrients are small enough to pass into your?
Intestine
What happens to nutrients in the esophagus?
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.
What part of the digestive process that takes the longest time happens in what oragan?
The longest part of the digestive process occurs in the small intestine. This organ takes several hours to digest food and absorb nutrients, as it is where most digestion and absorption of nutrients takes place. The small intestine's complex structure, with its villi and microvilli, maximizes nutrient absorption, contributing to the extended time required for this stage of digestion.
What is Outline the basic principles of digestion and absorption?
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.
What happens to digested food after absorption?
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.
Where does food leave the digestive system and into the circulatory system?
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.
Why do you think most digestion takes place in the small intestine?
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.
What happens to a sandwich when you eat it relative to events occurring in ingestion digestion absorption and elimination?
Well...It goes down the toilet.
What happens to the cell structure of fresh fruit once its liquidized?
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 what are they?

Absorption of the villi happens where?
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.
Why is the small intestine curled and furled?
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.
