2.WBCs- they are the defence Machanism of our body. when there is a foreign particle in our body, they protect the body. they are also responsible for making antibodies against pathogens and killing it.
3.platelets- platelets help in the clotting of the blood. whenever there is an injury and blood comes out, the platelets stop the flow of blood and form a layer at the place.
