Solution
-
The innate immune system, also known as the non-specific immune system, is the first line of defense against pathogens. It is called "innate" because it is present in the body from the time of birth and does not require previous exposure to a pathogen to be activated. It includes physical barriers like skin and mucous membranes, as well as immune cells like neutrophils and macrophages. These components work together to prevent the entry of pathogens into the body and to destroy any that manage to get in.

The cells of the adaptive immune system, which include T cells and B cells, are primarily found in the lymphatic system in humans. This includes the lymph nodes, spleen, tonsils, and the thymus. They are also found in the bone marrow, where they are produced, and in the blood, where they circulate to monitor for pathogens. The adaptive immune system is responsible for the body's specific immune response, which targets specific pathogens that the body has previously encountered.
