They are Secretaries.
There are several types of secretaries, including executive secretaries, who support high-level executives; administrative secretaries, who handle general office tasks; legal secretaries, specializing in legal documentation and procedures; and medical secretaries, who work in healthcare settings managing patient records and appointments. Additionally, there are also virtual secretaries who provide remote administrative support. Each type has specific skills and responsibilities tailored to their respective fields.
The President of the United States is also the "Commander-in-Chief" of all U.S. armed forces. His policies and directions are then carried out by the Secretary of Defense, and in turn by each of the service's own Secretaries (Secretary of the Army, etc.).
The president chooses the secretaries but then Congress must approve them.
Except for justice, the department heads are called Secretaries. The head of Justice is the Attorney General.
There are 15 departments within the US Executive Branch, headed by 14 Secretaries and the Attorney General. Each of the secretaries is responsible for the operation of his particular department within the government. (For these functions, see the related question)
The heads of the major departments in the executive branch are part of the President's Cabinet. They typically work in the Eisenhower Executive Office Building or their respective department buildings, such as the Department of State or the Department of Defense. The Cabinet includes the Secretaries of each department and advises the President on various issues and policies.
