The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
The process that occurs in the mitochondria is cellular respiration. It is on the cristae that cellular respiration occurs, where food is converted into another usable form of energy. Most of the energy producing reaction which occur in the mitochondria, happens in the surface of the cristae.

It is where the coronary artery is blocked by fatty plaques or blood clots. In this way, blood flow to the heart muscles is decreased or even cut off. This may lead to the damage of the cells and eventually the heart may not function.
