Is the innate immune system fast?
The cells and molecules of innate immunity are rapidly activated by encounter with microbes or other “danger signals.” The rapidity of the response is essential because of the fast doubling time of typical bacteria.
What is an example of acquired immunity?
There are two examples of passive naturally acquired immunity: The placental transfer of IgG from mother to fetus during pregnancy that generally lasts 4 to 6 months after birth; and The IgA and IgG found in human colostrum and milk of babies who are nursed.

Is stomach acid a part of innate immunity?
It includes the skin, mucous membranes, and other barriers to infection; lysozyme in tears, stomach acid, other antibacterial molecules, and numerous other factors belong to innate immunity. Phagocytes, natural killer cells, complement and cytokines represent key participants in natural innate immunity.
What are the 4 types of acquired immunity?

What is natural immunity?
Immunity: Natural immunity occurs through contact with a disease causing agent, when the contact was not deliberate, where as artificial immunity develops only through deliberate actions of exposure. Both natural and artificial immunity can be further subdivided, depending on the amount of time the protection lasts.
