What tissues are involved in wound healing: features of physiology

What tissues are involved in wound healing? To answer this question, we must first understand the structure and features of the organization of the main regenerating tissues of living organisms.

What is fabric

A tissue is called a collection of cells. They must necessarily be similar in structure and perform the same functions. From the tissues subsequently formed organs and their systems. The tissues of plants and animals have significant features. The former have practically no intercellular substance. The function of protection and interrelation with the environment is performed by the integumentary tissue, the basic mass of the organism is formed by the underlying tissue . Mechanical and conductive provide support and movement of the necessary substances. But the following plant tissue can be called "magic." It begins to work where it is necessary to restore the integrity of the body. It is called educational. Her cells are able to turn into elements of any tissue needed in a specific place in the body.

The structure of tissues of the human body

Animal tissues contain a certain amount of intercellular substance. The exception is epithelial. It is "borderline" and performs a protective function. Therefore, it consists of small closely fitting cells. In the human body, also the connective, muscular and nervous. What tissues are involved in the healing of wounds? First of all, those that consist of young cells capable of active division.

What tissues are involved in wound healing?

Such properties, first of all, have connective and epithelial tissues. The first, being the basis of the organism, are found in almost every organ. Especially rich in young, actively dividing cells granulation tissue. It is a kind of connective. Epithelial tissues complete the process of recovery. Each of them has its own mechanism of operation. Regardless of what tissues are involved in the healing of the wound, their structure is to a certain extent mutated.

Epithelial tissue

It participates in regeneration processes most often. After all, scratches and superficial superficial wounds are a consequence of careless behavior even in children. Their recovery occurs quickly enough. After all, this type of tissue regeniruet constantly. Its keratinized surface layer daily peels off by washing the skin, rubbing against clothing, etc. It has a great protective value, because together with the surface layer the body gets rid of dirt and pathogens. What tissues are involved in the healing of wounds? All epithelial cells are capable of active division. Including glandular, able to distinguish various secrets.

Connective tissue

This kind of tissue contains a lot of intercellular substance, because it forms the basis of the whole organism. Bones, cartilage, blood, fat - all these are connective structures. Consider what tissues are involved in wound healing. A special role in this process is played by granulation tissue. It quickly eliminates defects and protects the site of injury from penetration of pathogens. This is very important, because the inflammatory effect tightens the healing process and can lead to significant complications. The result of the activity of connective granulation tissue is the transformation of its cells into coarse-fiber. Visually, this manifests itself in the formation of a scar at the site of the dislocation.

Mechanism of thrombus formation

Disorders of healing processes and their direct course are also closely related to blood activity. It is also a connective tissue, which, due to the special properties of the intercellular substance, is liquid. In the mechanism of the healing process, colorless blood cells, leukocytes, are primarily involved. They neutralize foreign organisms and bodies by phagocytosis - intracellular digestion. This prevents inflammation. Pus often forms on the wound site. This is the body of dead white blood cells. Another protective mechanism is the formation of a thrombus. With mechanical damage, vascular integrity is almost always impaired, which can lead to significant blood loss. However, in a healthy body this does not happen due to the activity of platelets. If the blood vessels are damaged, they are destroyed. At this time, the plasma protein fibrinogen, which is soluble, is converted into fibrin. As a result of complex chemical transformations, a network of its filaments is formed, which prevents the blood from flowing out of the vessel. Violation of this process is called hemophilia. This disease is hereditary and is transmitted mainly through the male line.

The process of wound healing

The healing mechanism includes several processes that depend on the degree of damage. This constriction, the filling of wound defects with collagen protein strands and epithelialization. In an adverse course, inflammatory processes occur. To accelerate the healing process, it is necessary to create certain conditions: sterility and cleansing from dead cells.

So, in this article we have examined which tissues are involved in wound healing and what are the mechanisms of this process. A special role in it is played by connective and epithelial, while to a certain extent all groups of cells of a living organism are capable of regeneration.
