chyme


It is the food bolus, that is, a mass of food that is formed during the chewing phase of food, but when it is already digested by gastric acids inside the stomach. It has a not very solid consistency and is characterized by having an acid taste, as well as being covered by a subtle slimy substance. Chyme appears in one of the last phases of digestion: after the disintegration of food (turned into a ball, due to the movements of the tongue when it is introduced into the mouth) thanks to some enzymes and, as mentioned above to gastric juices.

The stomach, by releasing the substances that break down the food, begins a series of contractions, which seek to achieve their proper functioning. In the midst of these movements, a small homogeneous mass is formed that will begin a journey to the intestine. During a few hours this process is carried out and the food particles are very small, therefore, they must be of a small size so that they can easily enter their final destination. The pancreas begins to expel a substance that calms the effect of gastric juices, as well as the liver and gallbladder, thus speeding up the digestion process.

All the nutrients contained in the chyme pass into the blood, which transports them to the body and supplies the body with what it needs to function properly. If protein and minerals are not absorbed in the small intestine, what remains is eventually removed in the large intestine and then becomes feces, which is passed out of the body through the rectum.
