The species is the smallest among all group; it has only one
kind of organism. Through to the system
developed by Linnaeus, each organism is given a two-part scientific name that
consists of a genus name and a specific name. The words used for scientific
names are from the Latin and Greek languages. They sometimes seem difficult to
read and even harder to pronounce. Since the different species of organisms
number in the millions, it is necessary for scientists around the world to have
a common language to be able to identify any organism with accuracy. As you
know, people in different countries have different names for organisms. This
naming system prevents confusion.

Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
