Answer: It affected the first sentence POSITIVELY as the alarm sound by the immune system is the mechanism it uses to defend the body against harmful invading organism.
Explanation:
The body's immune system is the system of organs and cells involved in defending the body against foreign intruders.
The immune system sounds alarm through different mechanisms by its cells.
There are different cells of the immune system that plays roles in the defence of the body against microbe but the white blood cells play a major role in the search, recognition and elimination of foreign intruders. They equally have the ability to come out if blood vessels, swim slowly in tissue spaces and return to the circulation.
Thus, if traveling white blood cells detect an invader, they sound an alarm by recruiting more immune cells to the area through chemotactic mechanisms. This leads to accumulation of immune cells in large numbers around the foreign substances; and the reaction initiated and mediated by the immune cell lead to the removal of the intruder.
