Lymph Nodes
Clusters of lymph nodes are found in areas such as the neck, armpits, chest, abdomen, groin, and thighs. They contain lymphocytes—white blood cells that help identify and destroy bacteria, viruses, toxins, and abnormal cells. Swollen lymph nodes often indicate that your body is actively fighting infection.

Thymus Gland
The thymus produces T-cells, a type of lymphocyte that plays a critical role in immune defense by identifying and destroying foreign invaders.

Bone Marrow
Bone marrow is responsible for producing immune cells, including lymphocytes, which are essential for maintaining a healthy immune response.

Small Intestine (GALT / Peyer’s Patches)
The small intestine contains specialized lymphatic tissue that protects against harmful pathogens such as E. coli, salmonella, and other organisms linked to digestive and inflammatory conditions.

Tonsils
Tonsils act as a first line of defense, filtering pathogens that enter through the mouth and nose and helping prevent infections.

Spleen
The spleen filters blood, removes damaged cells, stores red blood cells and iron, and plays an important role in maintaining overall blood health and immune balance.
