Description of What Happens to Food During Digestion
Hi, I’m Stella Metsovas. And today, we’re talking about the description of what happens to food during the digestive process. This is a personal favorite subject of mine because I have devoted my career in digestive health research.
I truly do think it’s important that both kids and adults should know how their food is digested.
Because then you become more connected with the most important aspect of your body in terms of your overall health and that’s your digestive tract.
Digestion is defined as the process of changing food into a form that a body can absorb and use for energy. Or as the raw materials to repair and build new tissue. Digesting food is a two part process that’s half mechanical and half chemical. Mechanical digestion begins in your mouth with your teeth breaking down foods. Chemical digestion occurs at every point in the digestive system by releasing enzymes and other substances. That will eventually break down food to release the nutrients inside.
Then as food enters your esophagus, your salivary glands release saliva to help move the food through the esophagus. Digesting foods in the stomach then occurs by releasing stomach juice in the blend of enzymes and hydrochloric acid, otherwise known as HCL and a little it of mucus. The stomach juices begin the digestion of proteins. And the stomach’s contractions push the substances to the small intestines, where your body begins to pull out the nutrients in needs.
The small intestine is very important because the intestinal walls grab on sugars, amino acids, fatty acids, vitamins and minerals. Which are then sent often to your body for energy or as building blocks for new tissue.
Then after the small intestine has done its job, the remaining, which is usually dietary fiber moves into the large intestine. And the end is, well, you know, excreting.
