The institutions which constitute the main organs of the government of a nation are the legislature, the executive, and the judiciary. The legislature is responsible for making laws, which are then implemented by the executive branch. The executive branch, which is led by the head of government (e.g. president, prime minister), is responsible for implementing and enforcing laws, as well as managing the day-to-day affairs of the state. The judiciary, which is typically independent of the other branches, interprets the law and ensures that it is applied fairly and consistently. In this way, the three branches of government work together to ensure that the state functions effectively and that the rights and interests of its citizens are protected. While the civil service and the senate may be important institutions in some countries, they are not the main organs of government in a nation, as they do not have the same level of responsibility and authority as the legislature, executive, and judiciary.
