Digestive System – Simple Explanation
The Digestive System comprise of all the Organs of the body which help in converting the Food taken, in a form that can be absorbed by the Body for its Nourishment. Each and Every part of the Digestive System has its specific function to do; and what we can do about it is, “We can help them to perform their Intended Function Properly”
The Digestive System starts with:
The Lips and Teeth
The Mouth opening is furnished with Lips to open and close it and assist in picking up our food and in sucking up our drink; and, as much of our food is in solid form, and as the Stomach can take care only of fluid and pulpy materials, nature has provided a mill in the Mouth in the form of two arches, of semicircles, of teeth, which grind against each other and crush the food into a pulp. Make sure to use this Teeth Mill to its fullest; as in this fast moving life, we give very less time to grind our Solid Food; and this eventually becomes one of the Prime causes of poor Digestion.
In the bottom or floor of the Mouth, there has grown up a movable bundle of muscles, called the Tongue, which acts as a sort of Waiter, handing the Food about the Mouth, pushing it between the Teeth, licking it out of the pouches of the cheeks to bring it back into the Teeth-Mill again, and finally, after it has been reduced to a pulp, gathering it up into a little ball, or Bolus, and shooting it back down the Throat, through the Gullet, into the Stomach.
How the Food Reaches the Stomach?
Our body, then, has an opening, which we call the Mouth, through which our food-fuel can be taken in. A straight delivery tube, called the Gullet, or Esophagus, runs down from the mouth to a bag, or pouch, called the Stomach, in which the food is stored until it can be used to give energy to the body, just as the gasoline is stored in the automobile tank until it can be burned. Inside the Gullet, Food does not fall of its own, but each separate swallow is carried down the whole nine inches of the gullet by a wave of muscular action. By contracting, or squeezing down in rapid succession, one after another, they move the food along through the tube. The failure of these little muscles to act properly is one of the causes of Constipation and Biliousness.
The Small Intestine
When the food has been sufficiently melted and partially digested in the stomach, it is pushed on into a long tube called the intestine, or bowel. During its passage through this part of the food tube, it is taken up into the veins, and carried to the heart. From here it is pumped all over the body to feed and nourish the millions of little cells of which the body is built.
The Large intestine
This Bowel tube or Small Intestine, which, on account of its length, is arranged in coils, finally delivers the undigested remains of the food into a somewhat larger tube called the Large Intestine, in the lower and back part of the body, where its remaining moisture is sucked out of it, and its solid waste material passed out of the body through the Rectum in the form of the Feces.
