• Anatomy of the lymphatic system showing primary and secondary lymphoid organs

• A lymph node showing afferent and efferent lymphatic vessels

• Regional lymph nodes

• Lymph capillaries in the tissue spaces

• Nutrients in food are absorbed via intestinal vili (greatly enlarged in the picture) to blood and lymph. Long-chain fatty acids (and other lipids with similar fat solubility like some medicines) are absorbed to the lymph and move in it enveloped inside chylomicrons. They move via the thoracic duct of the lymphatic system and finally enter the blood via the left subclavian vein, thus bypassing the liver's first-pass metabolism completely.
