Best health tips for your life
Basically the digestive system process is a long tube that starts from your mouth, continued down to the throat to the stomach and then forwarded to the small and large intestine to the rectum and ends at the anus. In this journey, the food will be converted into chemicals that can be absorbed by the body for use as energy or build new body tissue.
Food Digestive System Process
Basically the process of food digestive system process is divided into two parts, namely :
Mechanical digestion. This process occurs in the mouth and stomach. Your teeth chew and break down food into smaller parts that you can swallow without choking. In your stomach, this process continues and continues to break down food into smaller particles.
Chemical digestion. Occur at any point in the digestive process in the body where enzymes and other substances such as hydrochloric acid ( derived from cells contained in the path to the stomach ) and bile ( derived from the gall bladder ) and then melt foods that release nutrients absorbed by the body.
Understanding Food Digestive System Process
This is the chronological digestion process of food in our bodies happens every day.
When you see the delicious food, the brain will respond by stimulating the digestive organs to get ready to receive food. While the scent of delicious food delivered through a molecule that fly from the surface membrane of the food toward your nose; stimulate the recipient cell ( receptor ) found on a nerve that extends from the nose to your brain.
When the recipient cells communicate with your brain, the brain will give orders to, drooling, heating the stomach and preparing for the small intestine. In other words, vision and smelling of food causes watery mouth ( drooling ) and reads as responding to your stomach feeling of hunger that appears.
When you lift the spoon towards your mouth, teeth, and then the salivary glands comes into action. Your teeth chew, crush, break the food down into smaller; so the results, you can swallow without choking and digestive enzymes help food digestive system process better.
At the same time, the salivary glands under the tongue and in the back of your mouth secrete fluids or saliva, which is useful for moisturizing and arrange food so that your tongue can push it to the back of the mouth and swallowed, and provides amylase (an enzyme that begins the digestion complex carbohydrates).
Your stomach is surrounded by powerful muscles that can perform a contraction called peristalsis. The goal is to move food through your stomach slowly towards the sort of place that mechanically break down food that has been destroyed after chewing into even smaller particles. While this process is running, the cells in the stomach wall secrete some sort of liquid in the form of enzymes, hydrochloric acid, and mucus (the mucus to protect the stomach from hydrochloric acid and enzymes).
One of the stomach enzyme called gastric alcohol dehydrogenase will digest a small amount of alcohol, which is not usually the nutrients can be absorbed directly into the bloodstream though you have not digested. Other enzymes, such as fluid from the stomach, initiate digestion of proteins and fats, separating it from the basic components of food ie amino acids (from protein) and fatty acids.
Mostly, hampered digestion of carbohydrates can happen even for a while; it hampered in the stomach, because the stomach is very acidic fluid that non-activate amylase, an enzyme in saliva that breaks down complex carbohydrates into sugar. Acid in the stomach can break some ties carbohydrates, thus digestion of carbohydrates also occur albeit slightly.
In the end, the food in your stomach contents mixed into a soup called chyme. When the soup is a little spilled past the stomach through the small intestine, the food digestive system process of carbohydrates continues and your body begins to absorb nutrients from food intake.
When the ‘ soup ‘ spilled from the stomach to the small intestine of this section, no new fluid is released participating, namely :
- Pancreatic and intestinal enzymes which complete the digestion of proteins into amino acids and help the digestive system process of fats and carbohydrates.
- Bile, a greenish colored liquid (made in the liver and stored in the gall bladder) which helps mix fats with water.
- Pancreatic alkaline fluid that helps to reduce acidity of ‘soup’ that amylase can help in total revamp of complex carbohydrates into sugar.
- Alcohol dehydrogenase in the gut that helps to digest alcohol which is not absorbed into your bloodstream.
When these chemicals are at work, peristaltic contractions move the food in the small intestine passes through a tube or hallway so that your body can absorb sugars, amino acids, fatty acids, vitamins, and minerals into the cells of the intestinal wall.
This is the large intestine and the main task is to absorb water from the food that cannot be absorbed and then squeeze it to fall behind the rest of the smells and excreted through the anus, known as feces. Stool is made of a material that cannot be digested foods, coupled with the cells lining the intestinal wall slough, and quite a lot of bacteria.
The roles of bacteria in the colon are breaking down undigested nitrogen, producing methane gas, carbon dioxide, and hydrogen. It also useful to produce fiber short chain fatty acids that protect cells from damage caused by colon cancer.
That’s the long journey of food in your body. Therefore, take care about your digestive health by eating healthy foods in order to work in accordance with its function. Hopefully, the article about digestive system process will be so much useful for you.
