Small intestine
The mouth and stomach both play parts in the digestive system ;also in chemical and physical digestion.In chemical digestion, in the mouth the saliva is mixed with enzymes which breaks down food into bolus and in the stomach acids break down the food turning it into chyme.In Physical digestion in the mouth the teeth tears the food and the stomach churns it.
The stomach would be the only part of the digestive tract that could be described as churning and mixing the food.
The primary mixing or churning organ in the human body is the stomach. It is responsible for breaking down food into smaller particles and mixing it with gastric juices to form a semi-solid mixture called chyme. The muscle contractions in the stomach wall help to churn and mix the food, aiding in digestion.
Segmentation in the digestive tract mixes food with digestive juices and increases the rate of absorption by repeatedly moving different parts of the food mass over the intestinal wall.
Digestion is a process involving mixing of food with digestive juices, moving it through the digestive tract, and breaking down large molecules of food into smaller molecules. Digestion begins in the mouth, when you chew and swallow, and is completed in the small intestine.
add fLAVOURING OR THE NATURAL JUICES
Fruit Juices are considered mixtures because when mixing two or more juices no chemical reactions take place, so they can not be called compounds etc.
salivary glands
the stomach
These waves of in the smooth muscles in the GI tract are call peristalsis.
The simple answer to this is "NO". After a meal depending on the type of meal( whether carbohydrate, fats or protein) the stomach undergoes a process of churning and mixing of the food with digestive juices. This enables easy absorption. 6 seconds is however too. Short for this process to occur. It takes approximately 2 hours for gastric emptying. Carbohydrate meals leaves faster than fatty meals which leaves faster than protein-rich meals.
I would guess at chewing the food and mixing with saliva before swallowing
