Secretory function of the pancreas, externally and intrasecretory activity, the endocrine part

As is known, the pancreas performs a number of tasks regulating the process of digestion, as well as the production of hormones necessary for the body. What are the features of the secretory function of the pancreas, and what varieties do they share?

It is important to note that the secretory task of the pancreas is divided into exocrine, intrasecretory, and also endocrine. As for the first, it is she who plays a key role in the formation of pancreatic juice containing enzymes for the subsequent splitting of food. Undoubtedly, the volume of the released fluid depends on many factors, in particular, on the food consumed and its quantity. On average, thanks to it, about 2 liters of juice are allocated during the day.

What is important, exocrine insufficiency can lead to the fact that the secretory task will not be performed by this body in full. There can be many reasons for this, and as a result, the digestion process is seriously disturbed, because due to external secretory dysfunction, the pancreatic juice is not released in the right amount and quantity.

Intrasecretory function of

The main task of intrasecretory function of the pancreas is to produce certain hormones in the amount that the body needs for normal functioning. It should be noted that all the allocated hormones: insulin and glucagon, regulate the amount of glucose, protecting against its possible excess or lack. Perform the secretory role of the corresponding cells, called the islets of Langerhans.

The incremental function of

The endocrine role of the gland, which is also often called endocrine, is really important for the body, because it regulates the amount of hormones in the body. Due to this, the pancreas suppresses the amount of insulin and somatostatin produced, thanks to which these hormones do not exceed normal values, and accordingly, sugar in the body remains in acceptable values.

The pancreas is an organ that performs a number of functions that are so necessary for the full functioning of the whole organism. It is due to the secretory function that the metabolism is regulated, the hormones necessary for controlling glucose level are developed, and their quantity in the body is regulated. Therefore, it is so important, so that the tasks of this body can be realized in full, without overloading it and thereby harming one's own state of health.

Pancreatic external activity of

The external secretory function of this organ is the excretory process in the duodenal gut of pancreatic fluid. This liquid contains enzymes( it is a question of lipase, lactase and so on).Pancreatic juice plays the role of neutralizing the acidic stomach environment, and also participates in the process of digestion.

It should be noted that, in contrast to the intrasecretory function, exocrine activity occurs only during the digestion of food, that is, when food enters the stomach. As a consequence, food components in combination with gastric juice can be named as natural pathogens of the exocrine activity of the pancreas.

The strongest factor in the appearance of pancreatic secretion is hydrochloric acid, which is part of the gastric juice. A sokonnym effect has such food as broths, decoctions of vegetables and various juices. The weaker sokorny effect has the usual water. As for alkaline solutions, they act on the pancreatic secretory function depressingly.

The external secretory function of the pancreas is regulated by the secretin route( with the help of hydrochloric acid, due to the action of which the hormone secretin is produced, which has a stimulating effect on the secretory activity).
