- Blood is mainly composed of two components- plasma and blood cells.
- Plasma is yellow coloured fluid part of the blood.
- Blood cells are of three types- RBCs, WBCs and platelets.
- RBCs are red in colour due to haemoglobin and functions in transport of gases.
- White blood cells and platelets are colourless. WBCs are involved in defense mechanism, while platelets participate in blood clotting.
- So, if we have only white blood cells in our body then the colour of the blood will be yellow due to colour of the plasma, since WBCs and platelets are colourless.
