Nyirokcsomókhoz translates to "lymph nodes" in English. Lymph nodes are small, bean-shaped organs found throughout the body. They are a crucial part of the lymphatic system, which plays a vital role in the body's immune defense and fluid balance. These nodes are strategically located along the lymphatic vessels, acting as filters for the lymph fluid that circulates through them.

Within the lymph nodes are specialized immune cells, primarily lymphocytes (T-cells and B-cells) and macrophages. As lymph fluid passes through, these cells inspect it for foreign invaders like bacteria, viruses, and abnormal cells, such as cancer cells. If a threat is detected, the immune cells are activated to mount a response, initiating an immune reaction to neutralize or eliminate the harmful substance. This is why lymph nodes can swell when the body is fighting an infection; the increased activity and proliferation of immune cells cause them to enlarge.

The lymphatic system also helps to return excess fluid and proteins from the tissues back into the bloodstream, maintaining proper fluid balance. Lymph nodes are situated in clusters in various regions of the body, including the neck, armpits, groin, and abdomen, allowing for efficient monitoring of lymph fluid from different parts of the body. Their involvement in immune surveillance and response makes them essential for maintaining overall health.
