The heart Hi, my name is Calvin and I am going to tell you about the heart. The heart is an important part of your body. Also it is a part of your cardiovascular system. And I got and retrieved these facts from Wikipedia.com. The parts of the cardiovascular system and the heart which helps you breathe; veins that transfer blood to body parts, arteries help you get air, and capillaries too. Some pieces of organs are bladder, kidney, brain, heart, tongue, and lungs. These help you breathe, eat, and urinate. The tongue has approximately 9,000 taste buds. Also 50 percent of germs are on your tongue. And 3,000 when you are a kid. So that is it. Bye. Also, special thanks to A.D.A.M.
