The digestive system works in a very sophisticated manner. Proper functioning of the digestive system is necessary to get energy for our day to day life.
Across the whole world, humans eat on average around between 1-2.7 kgs food a day that’s over 367 kgs a year per person, and every last scrap makes its way through the digestive system consists of 10 organs and off 9m length and also contains over 20 different specialised Cell types which help in absorbing a variety of nutrients.
The digestive system is one of the most diverse and complex systems in the human body; its parts continuously work in combination to fulfill an individual task.
It transforms the solid or raw materials of the food into the nutrients and energy for our day to day life.
What is the digestive system?
The digestive system is made up of the gastrointestinal tract, pancreas, gall bladder liver, and other different types of body enzymes, hormones, and essential blood.
The functions of each organ which plays a vital role in the digestion of food.
1. Gastrointestinal tract
It consists of a twisting channel. The primary purpose of the digestive tract is the transportation of food to the stomach; it has a vast internal surface area of 30-40 square meters which is more than enough to cover half a badminton court
2. Pancreas, Gall bladder, and Liver
Here the food is broken down using special juices released by these trios of organs
3. Body’s enzymes hormones nerves and blood
Various organs, different enzymes, and hormones work together to break down food, helps in modulating the digestive process, and delivering the final products.
It is made up of a vast stretch of tissue that supports and positions all our digestive organs in the abdomen, empowering them to do their tasks. The digestive process begins before even food enters your mouth, awaiting tasty morsel glands in your mouth to start to pump out saliva. We human beings produce around 1.5 liters of this saliva every day.
How digestive system works?
The digestion process starts even before the food entered into your mouth.
After the food is entered, we start chewing it with our teeth. Once inside your mouth, chewing combines with the sloshing saliva to turn food into a moist lump called bolus.
Enzymes present in the saliva break down any starch
then your foods find itself at the rim of 25 cm long tube called the esophagus down which it must plunge to reach the stomach
nerves in the surrounding esophageal tissue sense the bolus’s presence and trigger peristalsis.
A series of defined muscular contractions. That moves the food into the stomach where it’s left at the mercy of the muscular stomach walls,
which bound the bolus breaking it into chunks.
Hormones secreted by cells in the lining trigger the release of acids and enzyme-rich juices from the stomach wall that starts to dissolve
food and break down its proteins. These hormones also alert the pancreas liver and gall bladder to produce digestive juices.
After three hours in the stomach, the once shapely bolus is now turned into a bubbly liquid called chyme, and it’s ready to move into the small intestine. The liver sends bile to the gall bladder, which secretes it into the first portion of the small intestine called the duodenum.
Here it dissolves the fat floating in the slurry of chyme so that they can be easily digested by the pancreatic and intestinal juices that have leached on to the scene.
These enzyme-rich liquids crush the fat molecules down into fatty acids and glycerol.
For easier absorption into the body. The enzymes also carry out the final deconstruction of proteins into amino acids and carbohydrates into glucose.
This happens in the small intestine lower regions, the jejunum and ileum, which are coated in millions of tiny projections called villi.
These create a vast surface area to maximize molecule absorption and transference into the bloodstream. The blood takes them on the final leg of their journey to feed the body’s organs and tissues. But it is not over quite yet
extra fiber, water, and dead cells sloughed during digestion make it into the large intestine, also known as the colon.
The body drinks out most of the remaining fluid through the intestinal wall. What’s left is a soft mass called stool.
The colon squeezes this byproduct into a punch called the rectum, where nerves sense it expanding and tell the body when its time to expel the waste. The byproducts of digestion exit through the anus and the great food’s journey between 30-40 hours is finally complete.
Why is digestion important?
Digestion is important because if your metabolism is not suitable, your body will not be able to absorb the nutrients from the food. Essential nutrients will directly get out of your body through stool in the waste product if digestion is not proper.
Many peoples are suffering from gaining weight even though they eat a lot of food. The main reason why they don’t gain weight is digestion.
Their digestion system is not working correctly due to which the body can’t able to take out the juice from the food.
The digestive system breaks protein into amino acids and carbohydrates into sugar to give us energy.
Also, the reverse is right many people are eating less than only they are gaining fat in their body because their digestive system is not able to convert the fat and end up storing the fats in the body. Due to our belly comes out.
How to make a digestive system healthy and work properly
- Start taking high fiber foods; fiber helps in the digestion process
- Stop taking foods that are very high in fat.
- Stay hydrated, because for digestion food needs water.
Without water in your body, you may suffer from constipation. Drink at least 3-4 liters of water daily.
- Skip the harmful habits like drinking high caffeine drinks
- Exercise daily exercise helps in digestion when you exercise your body starts warming up, blood flow increases throughout the body, also helps in constipation.
