Getting to Know Our Digestive System. How it works?

Ever since we are children, the functions of the digestive system have already caught our attention. Even by simply licking a lollipop, we as children get amazed at how their tongues savor the sweetness of the food, and even just a friend's stomach “growl” is something to start giggling about. But then as we age, we begin to appreciate more how our digestive system works, beginning to keep in mind carefully why we should keep our digestive system healthy and clean. In general, we know that this “machinery”, otherwise called our gastrointestinal or digestive tract is responsible for the passage and breakdown of foodstuffs in our body, never taking a second off at duty.

The human digestive system is responsible for the taking in of food (ingestion), breaking food by physical or chemical means into substances that can be readily used by the body (digestion), transportation of food across membranes into the cells (absorption), and evacuation of the indigestible food remnants (defecation). All these functions are linked to the organs present in the digestive tract which are basically divided into two major groups: the organs that make up the alimentary tract, and the equally important accessory organs.

The four digestive functions of the gastrointestinal tract are altogether performed by the alimentary organs. The accessory organs serve as “helpers” that assist in both the physical and chemical breakdown of food – among the organs considered as “helpers” are the teeth, tongue, and a large number of digestive glands. Let us try to evaluate the function of some of the major organs that our gastrointestinal tract is most known of.

First stop: the mouth. Food enters the entire length of the hollow coiled tube (or the digestive) via the mouth or otherwise referred to as the oral cavity. Its opening is protected by the lips, and food is broken down mechanically into smaller particles by the teeth in a process called mastication. Digestive enzymes contained in saliva from the salivary glands are emptied into the mouth via ducts, and these assist in the breakdown of carbohydrates in particular. The saliva, aside from being an avenue for digestive enzyme secretion, is also bacteriostatic in nature, and it keeps the oral mucosa moist. Buffers in saliva are also a great help in the maintenance of oral pH within 7.0, thus helping relieve heartburn. Therefore it is important to keep the mouth clean in return for the favor!
