Yоu аre wаlking аrоund оutside... you go to pick a rose, and a thorn pricks your finger... delivering a small amount of bacteria into your tissues.  With that in mind, what happens next?  (see below)   A special type of immune cell which matures/reaches immunocompetence in your bone marrow is called a ____42_____.  It can ID pathogenic cells based off of their exterior cellular markers called _____43_____ and become activated.  When activated these cells develop into _____44______ which mark pathogens for death using special proteins called _____45____.  These marked cells are typically destroyed by _____46_____ which phagocytize them.  This is a description of a ____47_____ immune reaction. If this was an infection in your foot, and the perspective pathogen was flowing up from the foot via your lymphatic system, then this scenario is likely to have taken place in a structure you might call your ____48_____.  After this has all happened, you will have some cells remain in the body for years to come, staying ready to fight off that same pathogen... these remaining cells are called _____49_____.  In this whole scenario... would this be considered naturally acquired immunity or artifically acquired immunity?
