Answer:
Her immune system is exhibiting the second line of defense. This defense is part of innate immunity.
Explanation:
The situation above is related to the<em> body's immune system.</em>
The<em> immune system is the defense system in the body that enables an individual to fight against a particular disease or infection.</em> It defends the body through its three lines of defenses, <em>first line, second line and third line</em>.
The first line of defense refers to the outer covering or barrier of the human body such as the <u>integumentary system, particularly referring to the skin.</u> The second line of defense refers to non-specific immune cells such as <em>dendritic cell, macrophages and neutrophils.</em> The third line of defense refers to the <u>adaptive immune system. </u>This consists of highly specialized cells that removes the pathogens and inhibit their growth.
Nina is exhibiting the second line of defense because of her symptoms. The presence of her high fever means that her body is fighting the infection. It is at the second line of defense that the immune system helps protect the body.
This defense is part of the<u> innate immunity.</u> This is also called "Nonspecific Resistance." This type of immunity involves the immune system fighting the body's invader. It is nonspecific and doesn't target any individual. Inflammation and fever is part of this immunity.
Nina is exhibiting high fever, thus the defense is part of the innate immunity.
The American heart association changed ABC (Airway, Breathing, Compressions) to CAB (Compressions, Airway, Breathing) because when the ABC sequence to perform CPR was performed, people would spend so much time trying to open the airway that there was a delay in chest compressions making rescue breathes harmful. With the new CAB sequence people initiate chest compressions sooner and ventilation is only slightly delayed.
