Key Facts About Lymph
- Derived from interstitial fluid: Lymph originates as tissue fluid (interstitial fluid) that is not reabsorbed into capillaries. It is collected by lymphatic capillaries and returned to the bloodstream via the thoracic duct and right lymphatic duct.
- Similar to blood plasma but contains WBCs: Lymph resembles blood plasma in composition (water, electrolytes, proteins) but contains WBCs (mainly lymphocytes) and no RBCs or platelets in normal lymph.
- Fat absorption via chylomicrons through lymphatics: In the small intestine, long-chain fatty acids and monoglycerides are reassembled into triglycerides and packaged as chylomicrons, which are too large to enter blood capillaries. They enter lacteals (specialized lymphatic capillaries in intestinal villi) and travel via lymph to the cisterna chyli → thoracic duct → blood.
