The upper portion of the respiratory tract is the nasal cavity and the nose. The external nose forms the first and foremost respiratory tract area. Nose is the major part that is responsible in exchanging air with the atmosphere. It is responsible for the human survival.
There are two openings in a nose. These are called as nostrils. They are also called as exterior nares.

Nasal cavity is the place where the air that is inhaled will be purified and it is transported to various human parts. thus, when air contains any dust or impurities it will make you to sneeze thereby the air gets out of the nose through External nares
The sun's energy drives various processes on earth. One of these processes is photosynthesis in plants whereby light energy is converted into chemical energy by forming carbohydrates from carbon dioxide plus water, which is a process which usually gives off oxygen which animals need to breathe. Another process driven by the sun's energy could be evaporation of water into the air to form water vapour and clouds which then precipitate when cooled off over mountains so is involved in the water cycle.
