Human Heart ProcessThe human heart has four chambers, the right atrium, the left atrium, the left ventricle and the right ventricle. The human heart has so many amazing characteristics. The normal heart rate for adults is 120/80. The human heart weighs twelve ounces and beats seventy-two beats per minute, about the size of a human fist. Its blood flow has many functions and is extremely vital to our body. We couldn't survive without our heart. I will talk about the functions of our heart and the blood flow of our heart. I'll go into detail to let you know things you've probably never heard. Our heart, its four chambers and blood flow are very interesting and vital to our well-being. Many things can mess up the heart process and the way it works. I'll talk about all the ways that ruin it and I'll also cover the valves of the heart, which are important for the heart's blood flow. The human heart has two ventricles and two atria that make up four chambers. The heart includes the atria and ventricles. The left atrium and left ventricle make up the left side of the heart, while the right atrium and right ventricle make up the right side of the heart. Each side is important, but the left ventricle and left atrium are the most important and I'll tell you why. The left ventricle receives blood from the left atrium and pumps it into the aorta. The aorta pumps oxygenated blood to the rest of the body. If someone shot you in the left ventricle, you would definitely die. That's why it's the most important. It pumps blood to the rest of the body. The right ventricle is also important. The right ventricle receives blood from the right atrium and pumps blood into the pulmonary artery. The pulmonary artery has...... middle of paper ......use of death in America, in which all in part is due to cigarette smoking. The best way to keep your heart healthy is to eat well, get plenty of exercise and not smoke cigarettes. Our heart and its many functions all work together as one huge electrical system with the four heart valves as the command center that brings blood to support the rest of the body. If it weren't for our heart and its important work, we couldn't breathe or live. It is essential to keep it healthy. Our hearts are so important and I think sometimes we take that for granted. Our four rooms are our life. The better you take care of it, the better it works. It's a very fascinating and very long process, but it's important to keep in mind how vital this fist-sized organ is to our body. The four chambers of our heart form the foundation of our very existence.
