The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.
Digestion is an important body process where the food we eat, gets changed into substances which can be absorbed through the body. Many different organs together form the digestive system, these organs interact to digest the food. The human digestive tract seamlessly adapts to the of the wide variety of foods that people eat. It has evolved to collapse foods into their component nutrients and excrete waste efficiently. With lots of different organs playing a role in digestion, the humble digestive tract is actually a complex system.
Although we learn concerning the process of digestion in high school, most of us had other things on our minds back then. But understanding how your digestive system is supposed to work can help tremendously when it comes to overall digestive health – knowledge which could help you take better care of your digestive system, faster identify any possible digestive problems, and help you to definitely communicate more effectively with your doctor.
Liver-Esophagus Vein Connection
Veins that take blood in the digestive organs to the liver can back up the liver has a problem. These liver veins also interact with veins in the esophagus. When liver problems cause a backup of blood, the esophageal veins swell and could burst, causing severe bleeding.
Our mouths secrete approximately one liter of saliva a day
Saliva production through our salivary glands may be the first step in digestion. Saliva is predominantly made from water, but does contain other substances, and can be stimulated just by thinking about or smelling food. Food breakdown begins within our mouths through the process of chewing, and through enzymes present in saliva. Saliva both lubricates food for simple passage into the esophagus, and coats the food to protect our teeth and also the lining of our mouth and esophagus.
Dietary Fiber helps promote better digestion
What’s more is the fact that fiber has a number of other health benefits that allow the body to return to status quo, before it became subjected to harmful elements such as carcinogens and toxins from food. It has also been proven that soluble fiber is effective in combating high blood pressure and bad cholesterol.
Sterile Before Birth
The bacteria that populate the digestive tract and help in nutrient absorption aren’t present in the fetus. Babies acquire bacteria in the mother and the environment during birth and in the times after being born.
Esophageal Lining Changeable
Cells lining the esophagus differ from those lining the stomach, as stomach cells must protect against acid. Severe gastroesophageal reflux disease, which causes stomach acid to repeatedly enters the esophagus, can stimulate cells of the lower esophagus to change into cells like those of the stomach lining like a protective mechanism.
Outside the Body
Technically, the digestive tract isn’t inside the body but outside the body. It’s considered a canal that allows food in and waste out, however the food has to pass through the digestive wall to get in to the body proper.
The stomach has sensory receptors that send information with the vagus nerve to the brainstem, the bottom part of the brain. When the information indicates the presence of toxins, the brainstem triggers vomiting and nausea.
Bacteria May Cause Inflammation
The stomach requires a health reserve of good bacteria. Probiotics assisted in the process of anaerobic digestion in humans as well as with preventing a number of digestive ailments. Good bacteria is needed in order to effectively fight off harmful microorganisms within the stomach, which can cause any number of serious diseases.
