Here's why:
* Protective Cells: Lymph nodes are filled with white blood cells (lymphocytes), which are a crucial part of the immune system. These lymphocytes are responsible for identifying and attacking foreign invaders like bacteria, viruses, and parasites.
* Storage: Lymph nodes act as a storage and filtering center for these protective cells. As lymph fluid (a clear fluid that circulates throughout the body) flows through the lymph nodes, lymphocytes are activated and prepared to fight off infections.
* Small Cell Masses: Lymph nodes are small, bean-shaped structures located throughout the body, often clustered in areas like the neck, armpits, and groin.
