Sodium has one electron in its outermost principal energy level, also known as the valence shell.
Think for a second there, if cells make tissues, than tissues make organs. Now the fourth level of organization will be that organs make the organ system.

Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
The electron arrangement for sodium is 2-8-1. This means that sodium has 2 electrons in the first energy level, 8 electrons in the second energy level, and 1 electron in the third energy level. Sodium has 11 electrons in total.
The kidneys filter blood and control the level of salts.
The one that controls circulatory is the heart
The brain controls the nervous system.
BRAIN.
