Words to know

atrium (atria): An upper heart chamber that receives blood

ventricle: A lower heart chamber that pumps blood out

artery: A vessel carrying blood away from the heart

vein: A vessel carrying blood back to the heart

capillary: A tiny vessel, one cell thick, where things pass to and from cells

pulmonary: To do with the lungs

Common mistakes

Your child swapped arteries and veins. Arteries carry blood away from the heart; veins carry it back. A for away is a handy reminder.

Your child named a vessel by its oxygen. Vessels are named by direction: the pulmonary artery carries oxygen-poor blood away from the heart to the lungs.

Your child mixed up the heart's two sides. The right side pumps blood to the lungs; the left side pumps it to the body.
