Question

The adaptive (specific) defense system ________.

A) is an innate defense
B) issues an attack specific to particular foreign substances
C) includes the skin and mucous membranes
D) is the body's first line of defense against invading pathogens
E) provides mechanical barriers to the body

Answer 1

The adaptive immune system is the body's specific defense system that issues an attack tailored to particular foreign substances. It provides a highly specific and effective response to substances and organisms that do not belong in the body, and it has a memory system for long-term protection.

Step-by-step explanation:

The adaptive immune system is the body's second line of defense against invading pathogens. It is a specific defense system that issues an attack tailored to particular foreign substances. The adaptive immune system takes longer to respond compared to the innate immune system, but it provides a highly specific and effective response to substances and organisms that do not belong in the body. The system also has a memory system that allows it to respond with greater intensity if the body reencounters a pathogen in the future.
