Your Digestive System, What You Should Know
Have you ever tried to imagine the way your body processes the food you eat, use what is valuable, and eliminate the waste? Your digestive system is a complex structure that involves various components, organs, chemicals, hormones, and nerves in its process.
As you take a walk through the digestive system, it is essential to learn the functions of each organ in the system. Also, you can learn how each organ relates to the other to have a free-flow movement of food.
What is the Digestive System? The digestive system is a structure and a process involved in the movement and breaking down of food for absorption and assimilation into your body. The digestive system starts at the anterior part, which is the mouth. The food then travels through various organs for digestion to end up at the posterior part of the system, which is the anus.
Food and water digestive journey from the mouth to exit has to pass through the gastrointestinal tract (GI). It is in your digestive system, also known as the gut that you inhabit gut flora or gut microbiome (good bacteria). The gut microbiome is host to the immune system that helps you remain healthy.
The Digestive System, Organs and Functions
The digestive system has its organs arranged and grouped into two parts, the gastrointestinal tract and the solid organs that complement the digestion.
Gastrointestinal Tract Organs
The hollow, long, and twisting digestive structure is the gastrointestinal tract (GI) or digestive tract. It involves the following organs:
Mouth. The mouth is the entrance of food and the beginning of the digestive process. Chewing food breaks down big particles to smaller ones for easy digestion. While chewing food, your salivary glands release saliva mixed with enzymes to breakdown food. Your mouth is the initial stage of food digestion. After eating, you swallow the food to pass it to the esophagus.
Esophagus. The salivary enzymes continue with the digestion process during the period the food is in the esophagus. The esophagus then contracts its muscles pushing food down the GI system to the stomach.
Stomach. Food enters the stomach through the esophageal sphincter, a muscular valve at the base of the esophagus. The stomach is a pouch-like organ that can hold food long enough for digestion. The stomach then releases some acidic secretion and enzymes for food digestion. Some stomach muscles agitate the food systematically to aid digestion.
The food then moves to the small intestine through an opening by a muscular valve known as pyloric sphincter.
Small Intestine. In the small intestine, the digestion process continues using bile from the liver and some enzymes from the pancreas. The nutrients, calories, and about 80% of water content are absorbed in the small intestine. The remaining food after absorption then passes on into the large intestine, also known as the colon.READ MORE
