The health bar, colored green, on top, and the Mana bar, colored blue, on the bottom.
Mana is the resource of some champions necessary to cast most of his/her abilities. The mana pool is represented by a blue bar below the green health bar and two numbers ( # / # ) in the middle of it. The first one is your current amount of mana and the second refers to the maximum amount you can store. Mana regenerates over time and this rate can be increased with masteries and items.
At level 18, the base mana pool ranges from 
Poppy's 725 to 
Janna's 1454.
The most mana any champion can get is 8468, adding all mana per level runes, mana masteries, level 18 Janna's base mana, and with six fully charged 
Seraph's Embraces, 
Muramanas, or 
Tear of the Goddesses.
