It is the lymphatic system that the daily metabolism, the combustion and absorption of nourishing elements coming from the intestine happen. Lymph fluid carries lipids and lipid-soluble vitamins absorbed from the gastrointestinal tract. This is one of the next most important functions of the lymphatic system. The absorption of fats and fat-soluble vitamins from the digestion system and the subsequent transport of these substances to the venous circulation make the lymphatic system invaluable to the health of the body and, of course, the skin. Particularly the absorption of beta-carotene, (Vit A) metabolism of the lymphatic system lymph flows slowly; there is no ‘pump’ to accelerate the flow, and it relies on body movement (like walking) to help with transportation.
