Final answer:
Systemic arteries carry oxygenated blood from the left side of the heart to the rest of the body through the systemic circuit.
Step-by-step explanation:
The blood vessels connected to the left side of the heart that carry oxygenated blood to the rest of the body are systemic arteries. These arteries receive oxygen-rich blood from the left ventricle of the heart and distribute it to every organ of the body through the systemic circuit. The aorta and its branches are examples of systemic arteries that transport oxygenated blood to various body tissues.
