Where does the digestion of our food start?
Mouth
Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
What is the order of digestion in the stomach?
The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.
What is digested first in the stomach?
Carbohydrates, for example, break down the fastest. This explains why many recommend carb-heavy foods for a quick energy boost. Proteins take longer to digest and exit the stomach. Fats take the longest time of all.
How does the stomach empty?

Does food come out in order?
Research has shown that digestion happens no matter what order food is eaten. Digestion begins in the mouth by chewing food to break it down. The stomach acids further break the food down which passes to the intestines, and nutrients from the broken up foods are absorbed and used by the body.
How long does it take for your stomach to completely empty?

What is the first step in the process of digestion?
Mouth. The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
