What Are Veins and Arteries For?

• Have you ever wondered what veins and arteries are for?

Both veins and arteries carry blood. Arteries carry blood from the heart to the rest of the body, while veins transport blood back to the heart. In systemic circulation, arteries usually carry oxygen-rich blood, while veins carry blood with less oxygen and more carbon dioxide. However, there is an exception: the pulmonary arteries carry oxygen-poor blood from the heart to the lungs, while the pulmonary veins carry oxygen-rich blood from the lungs back to the heart (Hirsch, 2018; García, 2020).
