Largest artery in the body that carries freshly oxygenated blood from the heart to the tissues is the

• A. Aorta
• B. Pulmonary artery
• C. Superior vena cava
• D. Inferior vena cava

Answer: (A)

The aorta is the largest artery and its job is to carry freshly oxygenated blood from the left ventricle into the systemic circulation to reach all tissues. Its large diameter and thick, elastic walls help withstand and smooth the high pressure of blood leaving the heart, distributing it through major branches to the body. The other vessels don’t fit this description: the pulmonary artery sends blood to the lungs and isn’t the largest, and the superior and inferior vena cava are veins that return deoxygenated blood to the heart, not arteries delivering oxygenated blood to the tissues.
