Detailed explanation-1: -The third line of defence is called the immune response and is SPECIFIC. It involves the production of two types of lymphocytes (B and T cells) which are specific to the invading particle. They work together to attack the pathogen.
Detailed explanation-2: -Innate immune cells are the body’s first line of defense. They quickly respond to foreign cells to fight infection, battle a virus or defend the body against bacteria. T-cells and B-cells react when invading organisms slip through that first line using a process called acquired immunity (or adaptive immunity).
Detailed explanation-3: -What is the body’s third line of defence against pathogens? The third level of your immune system consists of cells tailor-made to get rid of the specific microorganisms that have invaded your tissue. Special cells called dendritic cells are the liaison (point of communication) between innate and adaptive immunity.
