Capillary resistance

Capillary resistance is the ability of capillaries to maintain the integrity of the vascular wall under the influence of mechanical factors such as pressure, stretching, compression, etc. Capillaries are very thin and fragile vessels that ensure the exchange of substances between blood and tissues. They play an important role in maintaining the body's homeostasis and are key elements in the regulation of metabolism.

The resistance of capillaries depends on many factors, including the elasticity of the vessel wall, the presence of proteins and other molecules in it, as well as the condition of the cells surrounding the capillaries. Normally, capillaries are highly resistant and can withstand significant mechanical stress, such as compression, stretching or pressure. However, under certain conditions, such as inflammation, injury or other diseases, capillaries can become more fragile and less resistant.

Increased resistance of capillaries can lead to various diseases, such as arterial hypertension, atherosclerosis, diabetes, etc. With arterial hypertension, for example, the walls of the capillaries become more rigid and prone to rupture, which can lead to damage to organs and tissues.

To maintain normal capillary resistance, it is necessary to monitor the health of blood vessels and lead a healthy lifestyle. This includes eating right, exercising regularly, giving up bad habits, and managing your stress levels. It is also important to monitor your blood pressure and control your blood cholesterol levels.

Overall, capillary resistance is an important factor in maintaining vascular health and preventing various diseases. Therefore, to maintain the health of blood vessels, it is necessary to monitor their condition and lead a healthy lifestyle.

The term resistance is translated from Latin as “resistance” or “stability”, and it reflects the property of capillaries, which are small blood vessels in the tissues of the body that maintain their integrity even under high intensity mechanical stress.

The resistance of a capillary is determined by its ability to prevent damage to its integrity in response to mechanical and chemical environmental factors. Mechanical stress can be caused, for example, by movement or compression of blood vessels, which leads to a change in their internal diameter and the formation of cracks in the capillary wall. Chemical factors, such as certain substances and metabolic products, can also influence resistance by causing changes in the composition and properties of the cells of the vascular wall.

When capillaries are highly resistant to mechanical and chemical influences, they ensure the normal function of organs and tissues in the body. However, with prolonged exposure to these factors or under certain conditions such as smoking, exposure to toxins, genetic predisposition, impaired blood supply and other factors, damage to the capillary wall or an increase in its permeability can occur. This phenomenon is called "reactive hyperemia"
