Digestion Cavity

The human digestive system is a complex set of organs responsible for processing food from the stomach into the blood and absorbing nutrients into the body. The digestion process begins even before food enters the mouth - starch is broken down into sugars in the mouth, proteins are broken down into amino acids, and fats are broken down into fatty acids and glycerol. Another important role in digestion is played by the oral cavity, where teeth and gums are actively involved in the mechanical grinding of food.

Digestion is the process of digesting food eaten. The speed of food digestion depends on the amount of food in the stomach, the degree of its filling and the amount of gastric juice produced. The separation of digestive juice occurs when food (chyme) enters the stomach from the duodenum, which is why it is often called gastric juice. Gastric juice consists of water, minerals and organic substances. It should be noted that the consistency and composition of gastric juice changes when eating food or changing the nature of its intake. For example, when breastfeeding the amount

Cavitary digestion (C.) is a process in which food passes through the digestive tract and is exposed to the action of enzymes contained in digestive juices. This process occurs in the mouth, stomach and intestines.

In the oral cavity, food is chewed, crushed and moistened with saliva. Saliva contains enzymes that help break down carbohydrates and prepare food for further digestion. The food is then swallowed and enters the stomach.

The stomach is a muscular sac that contracts and stretches to mix food with gastric juices. Gastric juice contains hydrochloric acid and digestive enzymes (pepsin and lipase), which help break down proteins and fats.

After food has passed through the stomach, it enters the small intestine where most of the digestion occurs. The small intestine contains many enzymes that break down carbohydrates, proteins and fats into simpler molecules. Also in the small intestine, nutrients are absorbed into the blood and lymph.

Finally, the food enters the large intestine, which serves for final digestion and removal of undigested food debris. In the colon, enzymes continue to break down complex carbohydrates and convert them into simpler ones. In addition, bacterial decomposition of undigested food occurs in the colon, which leads to the formation of gases and other metabolic products.

Thus, cavity digestion is an important process for our body. It begins with chewing food and continues until undigested residues are eliminated. Various enzymes and juices released during the digestion process help break down and assimilate the nutrients needed to sustain life.
