Read an Excerpt

Make a fist. This is about the size of your heart. Sixty to one hundred times every minute your heart muscles squeeze together and push blood around your body through tubes called blood vessels.

Try squeezing a rubber ball with your hand. Squeeze it hard once a second. Your hand will get tired in a minute or two. Yet your heart beats every second of every day. In one year your heart beats more than thirty million times. In an average lifetime a heart will beat over 2,000,000,000 (two thousand million) times.

The heart works hard when we relax or sleep and even harder when we work or exercise. It never stops for rest or repair. The heart is a most incredible pump.

Not all animals have hearts. There are tiny creatures in oceans and ponds that take in food and oxygen from the surrounding waters. But in humans and other mammals, most of the cells lie too deep within the body to get food and oxygen directly from the outside.

The human body is made up of hundreds of billions of microscopic cells. Your muscles, nerves, skin, and bones are all made of different kinds of cells. But every cell in your body needs food and oxygen, and your cells also need to be protected against germs that can cause disease.

Your heart, blood vessels, and blood work together to supply each of your cells with all of its needs. Every minute, the heart pushes a pulsing stream of blood through a network of blood vessels to every cell in your body. The constantly moving blood brings food and oxygen to each cell, carries away such wastes as carbon dioxide, and serves as an important component in the body's immune system. The heart, blood, and web of blood vessels make up your circulatory system.

This is an excellent book to go along with a science lesson. It talkes about the heart and its functions. It also covers blood, blood cells, arteries, veins, and other parts of the heart.

Having had a stroke that was caused by heart fibrilation I was eager to learn more about heart function. Most adult references were too complicated, so I resorted to a paperback that is meant for young reader understanding. It is in the youth reader files but was just what I wanted, simply put for general knowledge. CCoit

This book is about the human body heart. If you are interested in the heart you should read this book. It tells about how the heart works. This book also tells about how the heart makes blood flow, and how people get strokes and heart attacks. It also talks about how your heart will speed up; slow down, how strong it is and how big it is. You can learn about arteries and veins also. There are many awesome photographs of how your heart looks. It even says about how many times your heart beats a year, a day, and a minute. This book also talks about many more! If you are interested in the heart you should read this book. By: Jared
