Organisms causing disease are termed “pathogens”. While the Adaptive Immune System is primed to respond to a foreign substance specifically, the Innate Immune System also detects conserved or invariant components of microbes that are not found in “self".

Instructions

Briefly describe the responses that occur downstream of pattern recognition.

Responses should be in a short answer format, so there is no need to include an introduction, body and conclusion. Be specific and thorough with your answer. Your response should be at least 150 words long. If your answer is too brief you will lose points. An answer that’s longer than necessary won’t cause you to lose points, as long as everything you write is correct-don’t include irrelevant information!

C.

Anytime a foreign substance, even someone else's bone marrow, is introduced to a body, there is an extra risk of infection.
D.

A common complication of bone marrow transplants is infection, and doctor's don't want the infection to spread to others.
E.

It's a traumatic procedure, and any extra stress on their body could kill them.
