(Lymphatica 2025)
🌿 What Is the Lymphatic System?
The lymphatic system is your body’s hidden river of health. It is made up of:
• Lymph fluid 🌊 (a clear fluid carrying immune cells and waste)
• Lymphatic vessels 🛤️ (tubes that transport lymph)
• Lymph nodes & organs 🛡️ (filters and immune defenders)
Its main jobs: detoxification, fluid balance, and immune defense.
🟢 Lymph Nodes (Nodi Lymphatici)
Tiny, bean-shaped filters that trap waste, pathogens, and toxins.
✨ Major groups of nodes & their functions:
• Cervical Nodes (Nodi Cervicales) 🧑🦰
Filter fluid from head, scalp, and neck. Important in throat & sinus infections.
• Axillary Nodes (Nodi Axillares) 💪
Located in the underarms; filter lymph from arms, chest, and breasts.
• Inguinal Nodes (Nodi Inguinales) 🦵
Found in the groin; filter lymph from legs, pelvic organs, and lower abdomen.
• Mesenteric Nodes (Nodi Mesenterici) 🍎
Deep in the abdomen; filter lymph from the intestines (important in gut health).
• Popliteal Nodes (Nodi Poplitei) 🦶
Behind the knees; filter lymph from lower legs and feet.
🏛️ Lymphoid Organs & Their Roles
• Spleen (Lien) 🩸
Acts as a giant filter for blood, removes old red blood cells, and activates immune responses.
• Thymus (Thymus Glandula) 🌱
Trains immature T-cells (soldiers of the immune system). Most active in childhood.
• Tonsils (Tonsillae) 👄
Guards at the entrance of the throat. First line of defense against inhaled or ingested pathogens.
• Bone Marrow (Medulla Ossium) 🦴
Produces lymphocytes (B cells & precursor T cells).
• Peyer’s Patches (Aggregated Lymphoid Nodules) 🍽️
Located in the small intestine; monitor gut bacteria and immune balance.
🚦 Lymphatic Highways
• Thoracic Duct (Ductus Thoracicus) 💚
The largest lymphatic vessel. Drains lymph from most of the body into the venous blood at the left subclavian vein.
• Right Lymphatic Duct (Ductus Lymphaticus Dexter) 💙
Drains lymph from the right arm, right chest, and right side of the head/neck into the right subclavian vein.
📚 Quick Recap
• Nodes = filters (each region has a role).
• Organs = immune training & blood/lymph detox hubs.
• Vessels/Ducts = highways carrying fluid back into blood.
Your lymphatic system is the bridge between detoxification and immunity. 💧🛡️
