When the digestive system is not working properly your entire body is out of balance.
Make up of Digestive system
This enzymatic tract is made up of hollow organs – mouth, esophagus, stomach, small intestine, colon and anus. The big intestine is also known as colon-rectum. All these organs are lined by mucous membrane (mucosa).
The hollow organs from the digestive tract, the digestive system includes two solid organs viz. the liver and also the pancreas. These organs have the effect of secreting digestive juices (e.g. bile) which are circulated to the intestine through the small tubes, known as ducts.
The mucous membrane that lines the mouth, stomach and small intestine includes glands that secrete nutrients to help the digestion of food materials. The organs from the digestive tract also have a smooth muscle layer which helps in breaking down the meals particles. This smooth muscle layer contracts and propels the meals particles along the digestive system by a process called peristalsis.
It’s the gallbladder that stores this enzymatic juices secreted through the liver, until they’re required by the small and large intestines. Gallbladder is taken away in case of unavoidable disease conditions. A person without gallbladder can continue normal life, provided he/she takes certain precautions regarding his/her diet.
Process of Digestion
Food entering the mouth is masticated through the teeth and partly divided by the saliva. Then, the partly digested food passes the esophagus and travels on the stomach, where it’s digested by the acid secretions. The stomach has three major functions – storing the swallowed food, mixing the meals with the digestive juices and emptying the digested food towards the small intestine. The intestinal wall absorbs the useful nutrients that are transported to other areas of the body. Finally, the food leftovers proceed to the large intestines and therefore are passed out as feces. Thus, digestion starts within the mouth and finishes within the small intestine.
Importance of digestive system
When the digestive system is not working properly your entire body is out of balance. It’s important to maintain the health of digestive system because it breaks down anything we eat and absorbs the nutrients necessary for good health. When the digestive system is not working properly, your entire body is out of balance.
Interesting facts about the digestive system
• Mouth brings the food to a neutral temperature from either cool or hot such that it matched with the temperature of the digestive system.
• The daily saliva production is much more than we think and it happens even with the smell, taste or sight of the delicious food we like to eat.
• Food is propelled from esophagus to stomach downwards by a lining made of smooth tissues. This happens even against gravity when we stand on our head
• The 20-25 foot of digestive system is divided in three sections: uodenum, the jejunum and the ileum. Small intestine is 3.5 times the total body length.
• Finger like projections villi in small intestine increases its absorption area of food.
• Large intestine is smaller than small intestine and is only 5 ft long. The name is due their respective widths.
• Large intestine has three parts: cecum, colon & rectum. Hence colon & large intestine are not the same as believed.
