Morphofunctional Characteristics of Individual Organs of the Human Digestive System

Hryn V. H.
Abstract

Today, the growing trend of the prevalence of diseases of the digestive system is a very important issue not only in Ukraine but also around the world. This problem applies not only to practical areas of health care, but also to theoretical medicine. The study of the anatomical structure and functional state of the digestive system is the theoretical basis for the extrapolation of various pathological conditions in laboratory animals. Analysis of scientific sources showed a lack of comprehensive morphological studies of the human digestive system. The purpose of the paper was to study the features of some organs of the human digestive system in the morphological aspect by bibliographic analysis of literature. Materials and methods. This bibliographic analysis is based on published peer-reviewed articles, books, textbooks, monographs, abstracts of dissertations. For the purposes of this systematic review, literature search (concerning the study of the structure of the human digestive system) was carried out on the Internet, domestic literature sources, scientific and electronic libraries of Poltava State Medical University by the following keywords: "digestive system", "morphology", "gastrointestinal tract", "colon", "cаecum", "embryonic development of the digestive system". Results and discussion. Digestive system (Latin «systema digestorium») is a system of organs of various structures and functions formed in phylogeny, the importance of which lies in the perception, mechanical and chemical (enzymatic) processing and absorption of nutrients needed to compensate for energy and material costs in the body. Conclusion. Significant progress has been made in understanding the development of the human digestive system over the past two decades. The human digestive system is formed in phylogeny community of similar in structure and function of organs, the importance of which is the digestion of food, mechanical and enzymatic breakdown, absorption of breakdown products into the internal environment of the body and their transport to the liver. The structure of the gastric mucosa is well thought out for secretion and protection against low pH of gastric contents, which is regulated by hydrochloric acid. The pancreas, like the gland of external secretion, produces many digestive enzymes in an inactive form. Activation usually occurs in the lumen of the small intestine. The liver receives most of the nutrients absorbed through the portal vein and then uses them to synthesize many larger molecules

Keywords: digestive system, morphology, gastrointestinal tract, colon, cаecum, embryonic development of the digestive system
