    AS biology

    tissue fluid... no rbcs...though WBCs present.....higher pCO2...lower pO2....lower glucose conc. than blood thus mantaining diffusion gradient in blood....u get proteins...like fibrinogen...immunoglobulins...and u have r.b.cs ..u get low pCO2....LYMPH HAS W.B.Cs..more fat than tissue fluid...b/c...
