Explain how certain provisions of the constitution provide for checks and balances among the branches of government?

The system of checks and balances grew out of the separate institutions that share power under the Constitution of the United States. By the system of checks and balances, each branch of government exercises some control over the other branches. There are several ways this can be done. The executive can veto legislation passed by Congress. Congress, however, can override a veto by a two-thirds vote of each house. The federal courts can rule on the constitutionality of a law. The President can influence the courts by the people he appoints to the judicial branch. The Senate must approve such appointments.
