Adorable aorta pin looks bloody cute on you! The aorta sends oxygen-rich blood from the heart to the rest of the body. Attached to the heart's pumping upper left chamber, the aorta loops around, then dips into your torso, bringing blood to your lower body, tummy, pelvic area and legs. It's the body's biggest blood vessel! Blood is a liquid that flows inside every inch of your body through a network of tubes called your circulatory system. Your blood carries fuel, food and messages inside your body. It also provides defense and removes waste. Your blood visits every single cell, making deliveries and taking out the trash. Your circulatory system is powered by a powerful pump -- your heart! Printed aluminum pin measures 1.25" tall and was made in China.
