How Our Digestive System Works?

The digestive system of our body works with a fixed goal of breaking down all the foods and drinks that we consume.

The system breaks down our consumption and converts food nutrients into energy that our body stores and uses for functioning. [2]

The process of digestion begins in the mouth.

Food gets broken down into little pieces which get along with all the enzymes that secret from within.

Once swallowed, the food takes the path of the food pipe and reaches to the stomach first and then the intestines.

Both the stomach and intestines secrete digestive juices which incorporate with the food and extract the nutrients from them. [3]

The wastes then travel through the intensities towards the anus for excretion.Nausea occurs when there is a problem regarding this whole digestive process.

If anything starting from the food swallowing to the waste excretion goes wrong, that may result in nausea.

The large scale of food breaking happens in the upper abdomen of our body. So usually the symptoms of nausea develop in that area causing discomfort to you.

When the symptoms develop, our body reacts to this problem by creating the urge of vomiting.Sometimes the urge may end up in real throwing out.

Once our body throws out the semi-digested food, it starts to feel better. [3]
