Venule

Venous vessels flow into capillaries, from which all tissues of the body receive oxygen and nutrients. Without drainage of the venous vessels, normal metabolism will not work, muscle tissue will inhibit functionality due to lack of oxygen and nutrients. Lymphatic fluid emerges from the capillaries.

Venules are located in the groin and back, on the inner thigh and under the knee. The diameter is more from one to six millimeters. The venila is very thin, but if you glue two such venulas together, you can get a silicone tube, which in Russia is called a Peto catheter. In the West it is called an infiltration tube.

Aggravating circumstances. If you find a venous tumor in a vein without signs of inflammation or damage, it should be removed and treated with antibiotics. The cause of the appearance of venules can be small wounds. This can happen due to a poorly performed injection. There is such a thing as

Vienna: history and interesting facts

Vienna is the capital of Austria and one of the most famous cities in Europe. This city is rich in history and cultural heritage, and its history is of great interest to tourists and local residents. In this article we will look at some interesting facts about Vienna and its past.

History of Vienna

There are many versions about the origin of the city's name. The most popular version is that the Viennese name “Aun” or “Uen” comes from the name of the Celtic goddess of love and war, Aune. There are also opinions about the connection of the city’s name with the German words “wana” (banner) and

Venules are small vessels that can be found in almost all organs of the human body. They are part of the lymphatic system and serve to transport substances from tissues to the lymph nodes. Venules are very important for human health, as they play a role in metabolism and protecting the body from infections and diseases.

Venules are thin vessels with low blood pressure and no muscular wall. Their diameter can vary from 2 to 50 microns. Veins are mainly connected to lymphatic capillaries, which form the main components of the lymphatic network. The functions of venules include filtering waste from tissues, removing fluids and nutrients, and supporting the immune system.

One of the most important functions of venules is to protect tissues from viruses and bacteria. This is achieved through the work of immune cells called macrophages, which circulate in the lymph and capture foreign agents in the body. When macrophages recognize the virus, they quickly begin to multiply, engulfing the foreign agent and destroying it. This process is called phagocytosis.

In addition, venules are also essential for regulating fluids and salts in tissues, which helps maintain proper functioning of the body. If the venous network were not functioning properly, it could lead to a variety of problems such as edema and other organ dysfunction. That is why the venule must be kept in excellent shape, taking the necessary measures to prevent and treat diseases.

But, in addition, venules have an important role in storing glucose and fats, maintaining optimal energy levels in the body. When glucose levels decrease, the rate of fat breakdown in the body decreases, and vice versa. By regulating fat levels and increasing the amount of insulin secreted, the body can maintain optimal blood glucose levels, which in turn helps protect the body from diabetes and other metabolic problems.
