Tsentraalveeni

Tsentraalveeni, often referred to as the central vein, is a term primarily used in two distinct medical contexts: within the liver and within a vein.

In hepatic anatomy, the central vein is a small vein located in the center of each hepatic lobule in the liver. It is a key component of the liver's microcirculation, collecting deoxygenated blood from the sinusoids, which are small blood vessels within the lobule. From the central vein, blood then flows into larger veins, eventually draining into the hepatic veins and then the inferior vena cava. The health and function of the central veins are crucial for the liver's detoxification and metabolic processes.

In the broader context of vascular anatomy, a "central venous line" or "central venous catheter" refers to a type of intravenous access device. These catheters are inserted into a large vein, typically in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein), and advanced so that the tip terminates in a large central vein, such as the superior vena cava or inferior vena cava. Central venous lines are used for administering medications, fluids, or blood products, as well as for monitoring central venous pressure and for procedures like dialysis. The term "tsentraalveeni" might be used colloquially or in certain specific regional medical terminology to refer to these central venous pathways or the lines themselves.
