nyirokfolyadékban

Nyirokfolyadék, also known as lymph, is a clear to yellowish fluid that circulates throughout the lymphatic system of the body. It is derived from blood plasma that has leaked out of capillaries into the interstitial spaces, the areas between cells. This fluid is then collected by lymphatic vessels, which are part of the immune system.

The composition of nyirokfolyadék is similar to that of blood plasma but with a lower concentration of proteins. It contains white blood cells, particularly lymphocytes, which are crucial for fighting infections. It also carries fats absorbed from the digestive system, waste products from cellular metabolism, and foreign particles such as bacteria and viruses.

The lymphatic system plays a vital role in maintaining fluid balance by returning excess interstitial fluid to the bloodstream. It also transports fats from the intestines to the bloodstream and is a key component of the immune system, filtering out pathogens and abnormal cells. Lymph nodes, which are small, bean-shaped organs scattered along the lymphatic vessels, act as filters for the lymph, trapping harmful substances and housing immune cells that can attack them.

The movement of nyirokfolyadék is largely passive, driven by muscle contractions, breathing, and the pulsing of nearby arteries. Without active pumping mechanisms like the heart, the lymphatic system relies on these external forces to propel the fluid. Blockages or disruptions in lymphatic flow can lead to fluid accumulation, known as lymphedema.
