I do not understand what exactly your question is but,
The 3 branches are the <u><em>Executive</em></u> branch, <em><u>Legislative</u></em> branch, and <em><u>Judicial</u></em> branch.
The <em>Legislative</em> branch <em>makes the laws</em>.
The <em>Executive</em> branch <em>enforces laws or put them in action</em>.
The <em>Judicial</em> branch <em>passes the law</em>.
