Human hearts pump every drop of blood in the bloodstream throughout the body 24/7. Made up of four chambers, electric impulses make sure the heart continues to beat at a typical rhythm. Blue, unoxygenated blood enters the heart via the right atrium, and leaves to get oxygen from the lungs via the right ventricle. Once rich in oxygen, blood once again enters the heart, this time in the left atrium and out the left ventricle. Blood only flows one way through the heart, coming into the heart via veins and going out of the heart via arteries. All of EcoSmartDesigns' handmade, pewter charm jewelry designs are proudly made in the USA.
