Pancreatic juice is a liquid thatproduces pancreas. It resembles an alkaline, transparent liquid without color. The gland is located behind the peritoneum and joins the spine at the level of 1 and 2 vertebrae in the lumbar region. Approximately, in an adult, its weight is 80 grams, and its length is 22 cm. The pancreas has a head, body and tail. It consists of glandular tissue and excretory ducts. According to the latter, pancreatic juice moves into the duodenum. What composition does it have and what function does it perform in the body? This will be discussed now.
The composition of pancreatic juice
The composition of the pancreatic fluid includes the following components:
- creatinine;
- uric acid;
- urea;
- various trace elements.
A person produces about 1.5-2 per day.l pancreatic juice. The secretion is controlled by the nervous and endocrine systems. With a large amount of pancreatic juice that secretes iron, an acute and chronic stage of pancreatitis develops. With a lack of secretion, a person quickly loses weight, although he has an increased appetite and eats a lot. This is due to the fact that food is poorly absorbed in the body. Pancreatic juice plays a huge role in the process of digesting food. Its composition is more water. So, about 98 percent fall on it and 2 percent on the remaining organic elements.
Pancreatic juice and its enzymes
Pancreatic juice enzymes are divided into two groups: organic and inorganic. To organic include:
- chymotrypsin;
- trypsin;
- phospholipase;
- elastase;
- carboxypeptidase and other enzymes in the form of pro-enzymes that have the property to break down proteins, fats and carbohydrates during their digestion.
Inorganic enzymes include:
- amylase;
- maltase;
- lactase;
- lipase.
Pancreatic enzymes are quite aggressive. Therefore, the gland produces a trypsin inhibitor to prevent cells from self-digesting.
Pancreatic juice: function
For humans, the pancreas has a largevalue and performs many necessary functions. First of all, it produces a liquid that is necessary for the digestion of food. With this property, food entering the stomach is processed into substances that are further distributed throughout the body. It controls the digestion of pancreatic juice. That it contains all the enzymes necessary for digestion. It is very important that the acidity of pancreatic juice was not lower than 7, 5 PH and not higher than 8.5 PH. Pancreatic juice (pancreatic juice) is produced with each food intake in the stomach and becomes the main thing in the process of its digestion.
Features of proper digestion
Чтобы сок панкреатический выделялся в достаточном the amount and process of digestion passed quickly and smoothly, it is necessary to adhere to proper and healthy food, try to avoid eating spicy, fried and fatty foods. Such food will lead to increased stress in the work of the intestine and stomach, which will affect the unfavorable work of the pancreas.
Features of the juice that produces pancreas
There are three main phases of pancreatic juice production:
Brain. It is based on conditioned and unconditioned reflexes. By conditional applies:
- food visibility;
- her scent;
- the process of cooking;
- mention of delicious food.
In this case, pancreatic juice is secreted under the influence of nerve impulses that go from the cerebral cortex to the gland. Therefore, this process is called conditioned reflex.
To unconditionally-reflex influences include the production of pancreatic juice when irritated by food pharynx and oral cavity.
The brain phase is short and it produces little juice, but a large number of enzymes.
Gastric This phase is based on the stimulation of receptors by food,what entered the stomach. Due to this, neurons are excited and through the secretory fibers enter the gland, where juice is released under the influence of a special hormone, gastrin. In the gastric phase, juice has little salt and water, and many organic enzymes.
Intestinal. It takes place under the influence of humoral andnerve impulses. Under the control of the gastric composition that has entered the duodenum and the products of incomplete splitting of nutrients, impulses are transmitted to the brain, and then to the gland, as a result of which pancreatic juice production begins.
The influence of food on the production of pancreatic juice
In the rest period, the pancreas does notproduces juice pancreatic. In the process of eating and after it, the selection becomes continuous. Pancreatic juice, its quantity, functions in relation to the digestion of food, and the duration of the process depend on the qualitative values of the food and its composition. In large quantities produced pancreatic juice in the use of bread and bakery products. A little less for meat, but very little for dairy products. The pancreatic fluid, which has been isolated for the processing of meat and meat products, is more alkaline than that produced for other products. When eating fatty foods, the juice contains three times more lipase (compared to meat dishes).
The center of the digestive system is complexstructure, its components are in many parts of the brain. All of them are interrelated. The digestive center has many functions. Among them are such as:
- participates in the regulation of motor, suction and secretory function;
- gives a signal of hunger, satiety and thirst.
Hunger is the presence of sensations caused byneed to eat. It is based on the unconditioned reflex transmitted to the pancreas from the nervous system. It is better to eat small meals up to five times a day. Then the pancreas will function properly and without failure.
Take care of yourself and be well!
