APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Lymph fluid flows through the tissue that makes up lymph nodes, where the tissue filters and recycles lymph fluid that your body needs. The cells within your lymph nodes will attack, destroy and eliminate waste, especially foreign invaders, to help your immune system keep you healthy.

Detailed explanation-2: -The nodes act as a filter. They trap or destroy anything harmful that the body does not need. Inside the lymph nodes are white blood cells, also called lymphocytes. These white blood cells attack and break down bacteria, viruses, damaged cells or cancer cells.

Detailed explanation-3: -Lymph nodes are small, bean-shaped masses of lymphatic tissue along lymph vessels. They store lymphocytes and filter waste, bacteria and damaged cells (including cancer cells) from lymph.

Detailed explanation-4: -Major clusters of lymphatic nodules include: Tonsils: these are clusters of lymphatic tissue under the mucous membrane lining of the nose, mouth, and throat. Lymphocytes and macrophages in the tonsils provide protection against foreign substances and pathogens that enter the body through the nose or mouth.
