The major artery that supplies all other arteries with blood is the:

  1. aorta

  2. brachial

  3. carotid

  4. femoral

The correct answer is: aorta

The correct answer is A - aorta. The aorta is the major artery in the body that originates from the left ventricle of the heart and supplies oxygenated blood to all other arteries in the body. It plays a vital role in distributing blood to all tissues and organs, making it the main artery that supplies all other arteries with blood. The other options are specific arteries that are not the main supplier to all other arteries. The brachial artery supplies blood to the arm, the carotid artery supplies blood to the head and neck, and the femoral artery supplies blood to the lower extremities.
