venózna

Venózna is a term that refers to the venous system of the body. This system is responsible for carrying deoxygenated blood from the organs and tissues back to the heart. The veins are part of the circulatory system, working in conjunction with arteries, which carry oxygenated blood away from the heart.

The venous system is characterized by its network of vessels that, in many cases, contain valves. These valves are crucial for preventing the backflow of blood, especially in the limbs where blood must travel against gravity. The pressure within the veins is generally lower than in the arteries.

Conditions affecting the venous system are often referred to as venous diseases. These can include issues like varicose veins, where veins become enlarged and twisted, and deep vein thrombosis (DVT), a condition involving blood clots in deep veins. Phlebitis, or inflammation of a vein, is another related ailment.

The health of the venous system is important for overall cardiovascular function and the efficient delivery of nutrients and removal of waste products from the body. Factors such as age, genetics, lifestyle, and prolonged periods of immobility can influence venous health.
