The human body is a complex and fascinating organism. One of its many functions is to protect the host from bacterial invasion. It does this by secreting enzymes that break down proteins, as well as toxins that are harmful to bacteria. However, not all bacteria rely on these methods for survival; some have evolved adhesins, surface appendages which allow them to stick to surfaces and avoid being removed.

This blog post will discuss how your body protects itself from such invaders! This blog post discusses one way in which our bodies fight off invading microbes: through the production of specific antibodies known as IgA protease inhibitors (PI).

These PI provide protection against certain types of infections but do not affect others because they bind specifically with epitopes on the surfaces of microbes. It is important to note that these three enzymes all serve different functions and are often found together, including within a single cell. This means that when an invader enters your body, it must survive exposure to multiple defensive systems before it can colonize inside you; this makes for a much more difficult invasion process! The most potent defense system may be immunoglobulin A (IgA), also referred
