Analogous organs can be defined as organs, which show similar functions, but do not having common origins. Organisms that possess analogous organs do not share common ancestor as their organs are derived from different origins.
Examples of analogous organs include wings of bats, birds, and birds which are evolved independently, but share common function (flying).
When there is a cut on your skin, it gives bacteria and other organisms a gateway to enter directly into your bloodstream and could harm the body. By cleaning the wound, you prevent disease and infections from the bacteria.
