Answer» The correct option is: (a) 3 1 5 4 2 Explanation: Leucocytes are white blood cells. These comprise of neutrophils which provide protection to the body through phagocytosis of bacteria and thus act as scavengers. The basophils are the granulocytes which contain histamines and heparin. Heparin thins the blood to prevent clotting. Histamines dilate the blood vessels and increase the permeability of capillaries. Monocytes are of two types namely macrophages and dendritic cells. Acidophils take up a role in anti-allergic reactions and wound healing. The lymphocytes are B cells, T cells and natural killer cells. These are mainly involved in the immune responses by producing specific antibodies. |
