Describe the process by which a dose of microorganisms entering the body through a cut in the skin progresses through innate immune activation and recognition by the adaptive immune system, up to the point of T and B cell activation. Please discuss where this process occurs, and how the structure of the tissue it occurs in is relevant to the process.
