External supporting cells (s. sustentantes externae; synonym Claudius cells), or support cells, are specialized cells located on the surface of the organ and perform the function of supporting and fixing the structures inside the organ.
These cells play an important role in maintaining the shape and structure of the organ, as well as ensuring its functions. They can associate with and interact with other types of cells such as epithelial, muscle, and nerve cells.
Support cells can come in different types and sizes, depending on the specific organ. For example, in the lungs they may be in the form of thin fibers that provide support for air bubbles. In the liver, support cells can have a more complex structure and support the liver cells, as well as perform the function of filtering the blood.
The outer support cells can be damaged by various diseases or injuries, which can lead to disruption of their function and the development of diseases. However, due to their unique structure and function, support cells are an important element in maintaining organ health and function.
External supporting cells, or Clause cells, are a type of cell that is involved in maintaining normal body shape and function. These cells are located on the surface of internal organs, such as the liver, kidneys, heart and others, and ensure their stability and integrity. On the other hand, these cells can also participate in processes of adaptation to the environment, such as changes in hormone levels, absorption of nutrients and release of toxins.
Cells that support the internal tissues perform many functions, the most important of which are the formation of the outer membranes of the body and the protection of internal tissues from damage. They also regulate the movement of blood within the body, prevent damage to internal organs, and ensure balance between fluids in the body. In addition, supporting cells maintain homeostasis - a necessary state of the body in which the constancy of the internal environment is maintained.
The outer cells are supported by a dense microscopic shell of connective tissue and collagen fibers. These fibers are able to adapt to mechanical stress and maintain body stability even under extreme low/high temperatures, water gradients and gravity. In addition, they provide mechanical support to the body when organs contract and expand, that is, during breathing, sleeping, eating and urinating.
A layer of supporting cells, both internal and external, is involved in the formation of the endothelium, which lines the blood vessels in the body. This tissue protects the walls of blood vessels from damage, regulates blood flow throughout the vascular system, and also participates in the transport of oxygen and nutrients.
The mechanism of functioning of external supporting cells is closely related to their structure and chemical composition. The cell membrane contains large amounts of proteins, fats, minerals and protein compounds necessary to maintain optimal functioning. Shell components can also improve connections between cells and provide additional strength and shock absorption.
The main components of the shell are collagen, elastin, proteins and glucosamines. Collagen is a major protein that is one of the most abundant in the human body and is involved in a variety of biological processes related to health.
