Explanation

Lymph is derived from interstitial fluid and contains water, ions, nutrients, WBCs (especially lymphocytes), but lacks RBCs and large plasma proteins like albumin which cannot easily leave capillaries. It's essentially blood plasma without RBCs and some proteins. Lymph is not a secretion of RBCs, nor does it contain RBCs.
