PHYSIOLOGICAL AND ANATOMICAL CHARACTERISTICS OF THE DIGESTIVE ORGANS OF COMMON PIKE ESOX LUCIUS

Abstract

With further investigation of the physiology and anatomy of the organs of pike and bony fish in general, special attention is paid to the life pattern of these fish. Esox Lucius pike is primarily a fish that lives in fresh water bodies of Ukraine. There belongs to the kingdom of creatures, the chordov type, the pike-like series, the homeland of the pike, the pike type, and the original pike species. Therefore, all the diversity of the development and physiology of the pike is primarily related to the interconnections of various processes that represent one of the main functions of the body This is fish pickling. Therefore, with the investigation of the etching organs and their functions, we looked at the detailed life of the fishing rod and their physiological function in the pike. The pike, like the pike, has a very large boat to accommodate a lot of pike, other fish, splitting and reshaping the living stern. Everything is explained by the method of creation and life of this type of fish. The statistics included the physiological and anatomical features of the visceral organ system of the pike, and the etching apparatus itself. The system of poisoning organs of the pike, similar to those of other creatures, looks like a tube with various swellings and begins with the oral cleft and ends with the anal opening. Vaughn is the longest-running system in the middle of the interior. Anatomically, the system of organs of poisoning is divided into the descending organs of the foregut, midgut and hindgut. Our research is aimed at studying the physiology and anatomy of the foregut of the pike, and the fishing rod itself. These organs are found in the second empty body of the pike as a whole. In general, the vernal sac is topographically expanded from the caudal end of the zebra plate to the anal opening. They are bordered dorsally by ridges, on the sides by ribs and visceral meatuses. The main body, or the whole transverse webbing, which is stretched along the level of the pectoral swimmers, divides the main part into two parts. The anterior part is the cardiac bursa, where the heart is located, and the posterior part is the central caelum, which contains the empty visceral organs. The cauterus of the pike is usually lined with a parietal leaf of greenery, a brilliant white-blakyte color, which extends to the internal organs and is also called the visceral leaf. It opens the internal organs, fixes and trims them up to the body of the pike. The passage of the pike initially begins from the pharynx topographically at the level of the shoulder girdle of the pectoral swimmers and extends until it enters the vulture until the cardial opening of the vulture. The organ of pikes is small, like a tubular organ, and contains serous, pulpal and mucous membranes. The mucous membrane forms later folds, its white color is lined with rich spherical epithelium, there are no herbaceous veins and without clear boundaries it passes into the scutum. The pike has a large hook, it has the power to stretch out greatly and its shape lies on the surface, so it is not cut when it comes to the line. The shunt takes the shape of a modified expanded sac in the surface, like a tubular organ, and performs mechanical and chemical functions. In the upper part, it occupies the entire ventral part of the calves. Anatomically, the scutum has the inlet cardiac opening and the outgoing poloric opening, which forms the sphincter, in the form of the pelloric valve, and passes into the small intestine. The mucous membrane has folds, is lined with a single-spherical cylindrical epithelium, and contains sulcus grooves. Slag juice has an acidic middle and undergoes the first pickling phase.
