Is it true that the arterial system of the human body is divided into systemic arteries carrying blood from the heart to the whole body, and pulmonary arteries, carrying deoxygenated blood from the heart to the lungs.

The answer is true.

Humans have a double circulatory system having two pathways - systemic and pulmonary.

The systemic circulation is between heart and body, and the pulmonary circulation is between lungs and heart. Both systemic and pulmonary arteries carry blood away from the heart, however systemic arteries carries oxygenated blood to body parts and pulmonary arteries carry deoxygenated blood to lungs for oxygenation.
