February is the time of year we exchange valentine cards, eat candy hearts, give candy in a heart-shaped box… Sometimes we cross our heart when we give our word to someone. Sometimes we sing about how our heart is overflowing with love for someone or something, or how our heart was broken. I don’t know about you, but I don’t ever think my heart has actually been broken, maybe bruised a bit, but not broken. Whew! Thankfully, most of have healthy beating hearts.
Your heart is really a muscle, but it not shaped like a valentine. It's located just to the left of the middle of your chest (between your lungs), and it's about the size of your fist, and it looks red like meat. The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs, and it carries away waste.
Have you ever wondered what your heart sounds like? Try building a stethoscope in this activity so you can listen to your heart.
