Identify the option that specifies the correct components of blood.
Red Blood Cells, White Blood Cells, Platelets, Plasma
Blood contains three cellular components and the fluid part, plasma. The three types of cellular components are Red Blood Cells (which give blood its distinctive red colour), White Blood Cells (which look white or transparent under a microscope) and platelets. The plasma is the liquid portion of blood which is made up of mostly water and dissolved nutrients.
