How the president as leader of national government uses departments to run the country?

The president, as the leader of the national government, utilizes various departments to implement policies and manage the administration of federal functions. Each department is responsible for specific areas, such as defense, education, or health, allowing for specialized management and expertise. The president appoints heads of these departments, who then carry out the administration's agenda and ensure compliance with laws and regulations. This structure enables efficient governance and the ability to respond to national issues in a coordinated manner.
