Hints & Solutions
(b) Basophil is a type of white blood cell (leucocyte) that has a lobed nucleus surrounded by granular cytoplasm. Basophils are produced continually by stem cells in the red bone marrow & move about in an amoeboid fashion. Like, mast cells, they produce histamine and heparin as part of the body’s defences at the site of an infection or injury. Heparin is a naturally occurring glycosaminoglycan produced in the body by liver, lungs, and other tissues from basophils and mast cells. It is injected into muscle or blood to prevent or dissolve blood clots. 0
