Your heart is one of the most important organs in your body. It pushes your blood throughout your body, bringing oxygen and nutrients to your cells. Your blood also takes away dead cells, poison, and excess water. Without the heart doing its job, you would die. In fact, if your heart stops beating, you die in about four minutes! How much does your heart weigh? How much blood does your heart pump every day? How many times does your heart beat every year? Do babies' hearts beat faster or slower than adults? And many more.
