Consists of a fluid called lymph, vessels called lymphatic vessels that transport the lymph, a number of structures & organs containing lymphatic tissues & red bone marrow.

The major difference between interstitial fluid & lymph is?

Location; interstitial fluid is found between cells, and lymph is located within lymphatic vessels & lymphatic tissue.
