Gastric Digestion: Understanding the Process

Digestion is an important process that allows our body to obtain essential nutrients from food. In this case, several stages of digestion are distinguished, each of which performs its own function. One of these stages is gastric digestion, which occurs in the stomach cavity under the influence of the juice of the gastric glands.

The stomach is the enlarged part of the esophagus, which is located between the esophagus and the duodenum. It plays an important role in digestion as it softens food and further processes it. However, in order for gastric digestion to take place effectively, certain conditions are necessary.

When food enters the stomach, it begins to contract and mix the contents. This helps in grinding the food into smaller pieces which can then be more easily digested. But the most important thing that happens in the stomach is the secretion of gastric gland juice.

The juice of the gastric glands contains several types of enzymes that help break down proteins, fats and carbohydrates. One of the most important enzymes is pepsin, which breaks down proteins into smaller particles - peptides and amino acids. In addition, the juice of the gastric glands also contains hydrochloric acid, which helps kill bacteria and other microorganisms that may be in food.

Interestingly, the process of secreting gastric gland juice occurs only when there is food in the stomach. If the stomach is empty, then the secretion of gastric gland juice stops. This is because the juice of the gastric glands is very acidic and can damage the stomach lining if not neutralized by food.

After food has been processed in the stomach, it enters the duodenum. Here another stage of digestion already occurs - intestinal. During the process of intestinal digestion, nutrients from food are absorbed into the blood and transported throughout the body, providing it with energy and necessary substances.

Thus, gastric digestion plays an important role in processing food and preparing it for further absorption. The juice of the gastric glands contains enzymes that help break down proteins, fats and carbohydrates, as well as hydrochloric acid, which kills bacteria and other microorganisms. But in order for the gastric digestion process to proceed effectively, it is necessary to follow the correct diet and not overeat. It is also important to consider possible gastric digestion disorders, such as gastritis, stomach ulcers and other diseases that can lead to serious consequences.

Overall, digestion is a complex process that provides our body with essential nutrients. Gastric digestion plays an important role in this process, ensuring the grinding of food and the breakdown of proteins, fats and carbohydrates. Therefore, in order to maintain the health of the body, it is important to monitor the correct diet and take into account possible digestive disorders.

The stomach is the first external section of the digestive tract in the digestive canal, in which continuous physiological and mainly chemical processing of food gruel that enters it from the human esophagus occurs. Its total volume occupies about 3.5 liters, which includes 4% of the total volume of hydrochloric acid produced by the body. The walls of the stomach can stretch
