I will mark whoever answers correctly will get marked as the brainliest!!!!!!!!! How does the human digestive system work and why is it so complicated?

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.A diagram of the human digestive system.

In a nutshell, digestion involves breaking down large food molecules into water-soluble molecules that can be passed into the blood and transported to the body’s organs.

For instance, carbohydrates are broken down into glucose, proteins into amino acids, and fats into fatty acids and glycerol.

The digestive system involves “hollow” organs and “solid” organs.

Food travels through the hollow organs — mouth, esophagus, stomach, small intestine, large intestine, and anus.

The solid organs — pancreas, liver, and gallbladder — add various products into the mix.

Aside from the solid and hollow organs, the nervous and circulatory systems are also important in digestion, as are the bacteria that live in the gut.

Answer:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules, digestion is a complicated process that takes place in our gut. Although food contains all of the nutrients we need for good health, they are locked up in large, complex compounds. So that they can be used by the body, they must first be broken into smaller parts by the process of digestion.
