Difference Between Aorta and Artery l Aorta vs Artery

The key difference between aorta and artery is that the aorta is the biggest artery that carries oxygenated blood from the heart, while artery is a blood vessel that carries oxygenated blood into other organs, tissues, and cells in our body.

The heart is one of the main organs in our body. It provides oxygen and all the other necessary nutrients to our body parts. Thus, the heart pumps blood through blood vessels, and the whole body gets nourishment via this circulatory system. Blood vessels are of three types; arteries, veins and capillaries. Arteries carry blood away from the heart, mainly oxygenated blood from the heart. Capillaries facilitate the actual exchange of water and chemicals between blood and tissues. Veins carry blood from the capillaries back to the heart. Aorta and pulmonary artery are the two main arteries directly connected with the heart.
