Digestion and absorption are the two intermediate processes from the entry of food into the oral cavity to its utilization, the specific differences are as follows:1. Digestion: through the movement of the digestive tract, food is ground up and mixed with the digestive juices of the gastrointestinal tract, and at the same time, the mixed chyme is pushed forward to the distal end, which, in short, is to turn the large molecules into the small molecules.2. Absorption: it refers to the absorption of chyme particles into the bloodstream from the gastrointestinal tract through the capillaries and, through the circulation of the blood into the The liver, through the first pass elimination effect of the liver, and finally distributed in all tissues and organs of the body, play a nutritional role, known as absorption. In short, digestion and absorption processes complement each other, poor digestion affects the effect of absorption, if the absorption function is poor, will also cause indigestion symptoms. In daily life, try to eat more light, warm and soft, easy to digest food, avoid spicy, cold and other stimulating food intake, to promote food digestion and absorption ability.
