Being very busy at work is like being covered with things or surrounded by something such as water or the ground, so that you cannot move easily. 1  They keep piling more work on me. 2  Iâm up to my eyes/ears/eyeballs/neck in work.  Iâm drowning in paperwork.
Adaptive Immunity Definition. Adaptive immunity is an important part of the immune system. It is protection from an infectious disease agent that is mediated by B-and T-lymphocytes following exposure to specific antigen, and characterized by immunological memory.ell-mediated immunity does not involve antibodies but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
An immune response is generally divided into innate and adaptive immunity.Innate immunity occurs immediately, when circulating innate cells recognize a problem. Adaptive immunity occurs later, as it relies on the coordination and expansion of specific adaptive immune cells.n effective vaccine will optimally activate both the innate and adaptive response. An immunogen is used to activate the adaptive immune response so that specific memory cells are generated.
