Which one of the following is correct?

  • Plasma = Blood – Lymphocytes

  • Serum = Blood + Fibrinogen

  • Lymph = Plasma + RBC + WBC

  • Blood = Plasma + RBC + WBC + Platelets

Answer

D.

Blood = Plasma + RBC + WBC + Platelets

Blood contains Red Blood cells (RBCs), White Blood cells (WBCs) and platelets (-45% of volume) suspended in plasma (~ 55% of volume).
Lymph contains WBC especially lymphocytes, floating in lymph plasma.
Serum is the part of blood that is like water and that contains antibodies which fight against disease.
Blood plasma is pale yellow liquid component that contains water (up to 95% by volume) and dissolved proteins (6-8%) which contains serum, globulins and fibrinogen and also glucose, clotting factors, electrolytes (Na+, Ca2+, Mg2+HCO subscript 3 superscript minus comma space Cl to the power of minus etc).
