Epitheliocyte Superficial

Surface epitheliocyte: functions and properties

The superficial epithelial cell (Epitheliocytus superficialis, LNH) is a cell of epithelial tissue that is located in the upper layer of the epithelium. These cells perform a number of important functions related to protecting the body from external influences.

One of the main functions of epithelial cells of the surface layer is to protect tissues and organs from mechanical damage and infections. The cells of this epithelial layer form a barrier that prevents the penetration of harmful substances and microorganisms into the body.

Epithelial cells of the superficial layer also play an important role in regulating the transport of substances through the epithelium. They control the processes of absorption, transportation and excretion of various substances in the body.

In addition, epithelial cells of the surface layer are involved in metabolism and the synthesis of hormones and other biologically active substances. They also take part in the regulation of the immune system, releasing biologically active substances that attract immune cells to the site of inflammation or infection.

The epithelial cells of the surface layer have a special structure that allows them to perform their functions. They have many microvilli, called microvilli, which increase the surface of the cells and improve their ability to transport substances.

In addition, epithelial cells of the surface layer have a large number of small vacuoles, which contain various substances necessary to perform their functions.

In conclusion, epithelial cells of the superficial layer play an important role in protecting the body from external influences, regulating the transport of substances and metabolism. Their special structure and properties allow them to perform these functions at a high level.
