Detailed explanation-1: -Macrophages: are another type of phagocyte and have a role in both the innate and adaptive immune systems. They attack foreign substances, infectious microbes and cancer cells. Macrophages also stimulate lymphocytes and other immune cells to respond to pathogens.
Detailed explanation-2: -Natural killer cells attack cancer cells or cells that are infected with a virus.
Detailed explanation-3: -Your thymus is a small gland in the lymphatic system that makes and trains special white blood cells called T-cells. The T-cells help your immune system fight disease and infection. Your thymus gland produces most of your T-cells before birth.
Detailed explanation-4: -T lymphocytes develop from a common lymphoid progenitor in the bone marrow that also gives rise to B lymphocytes, but those progeny destined to give rise to T cells leave the bone marrow and migrate to the thymus (see Fig. 7.2). This is the reason they are called thymus-dependent (T) lymphocytes or T cells.
Detailed explanation-5: -They quickly respond to foreign cells to fight infection, battle a virus or defend the body against bacteria. Our acquired immunity-also called adaptive immunity-uses T-cells and B-cells when invading organisms slip through that first line.
