The passage above from Article 1, Section 7 of the U.S. Constitution reflects the principle of CHECK AND BALANCE.
The legislative branch is tasked to make the laws, the executive branch is tasked to make the laws official and executory, the judicial branch is tasked to review the laws based on its constitutionality and oversee the court system.
These separate branches have their own duties and responsibilities but they all share the same power. The power of any one branch is checked and balanced by the other two branches to ensure that no abuse of power is committed.
