Inner shell (Intima, Tunica Intima)

Internal tunica (Intima, Tunica Intima) is the inner layer of the wall of an artery or vein. It is formed from the endothelial cells lining it and an elastic membrane.

Also, the term "tunica internal" can refer to the inner layer of any other organs or parts thereof. The inner membrane performs a barrier function, separating organ tissue from its cavity or lumen. It regulates the molecular transport of substances through the organ wall. In the case of blood vessels, the inner lining is also involved in the regulation of vascular tone and hemostasis. Damage to the inner lining can lead to dysfunction of the corresponding organ.

The tunica intrinsic is the inner layer of the wall of an artery or vein, which is formed from endothelial cells and elastic membranes. It is an important part of the circulatory system and performs many functions, including protecting the inner walls of blood vessels from damage, regulating blood pressure, and transporting oxygen and nutrients to the body's tissues.

In addition, the inner lining may form the inner layer of any other organs or parts of the body, such as the lungs, kidneys, liver, heart, gastrointestinal tract, etc. It also plays an important role in maintaining the health and function of these organs.

The inner shell consists of several layers, each of which has its own function. The first layer - endothelial - is a layer of cells lining the inner surface of blood vessels. It provides protection from damage and regulates blood pressure. The second layer - the basal one - consists of elastic fibers that provide flexibility and stability to the blood vessels. The third layer, pericytes, are specialized cells that maintain the structure of blood vessels and regulate blood flow.

Violation of the structure of the inner lining can lead to various diseases, such as atherosclerosis, thrombosis, stroke, myocardial infarction, etc. Therefore, it is important to maintain the health of the inner lining and monitor its condition. This can be done through a healthy lifestyle, proper nutrition, physical activity and taking vitamins and minerals.

The inner lining (intima, tunica intima) is the inner layer of the wall of any artery or vein, which is formed from the endothelium lining it (endothelial cells) and the elastic membrane. It plays an important role in maintaining the smoothness and elasticity of the walls of arteries and veins, as well as in regulating blood flow.

The inner layer is the first layer of the vascular wall and consists of three main components: the endothelial lining, the tunica intima and the adventitia. The endothelial lining is a flattened monolayer of elastic cells that are located on the inner surface of blood vessels. These cells are responsible for regulating blood pressure, preventing blood clots and the interaction of blood with other layers of the vessel wall.

The tunica intima is the middle layer of the inner tunica, consisting of a thin inelastic membrane that contains a number of proteins such as collagen, elastin and other proteins responsible for the strength and elasticity of blood vessels. This layer provides blood flow capacity and determines the speed of blood flow between the layers of the artery or vein wall.

The tunica adventitia is the outermost layer of the tunica interna and covers the outer surface of blood vessels. It consists of connective tissue and collagen, and protects the inner lining from mechanical damage and plays a role in vascular regeneration.
