Heart disease is a serious problem. About five million people in the United States suffer from the disease. Many people with heart disease need new hearts. They have to wait until doctors have hearts to give them. Some people die waiting. Now, there has been an exciting new heart experiment. Scientists hope this experiment will help them to save thousands of lives.Dr. Doris Taylor manages a heart center. She led the team of scientists that succeeded in building a rat heart in a laboratory.The scientists began by removing the hearts of several rats. They then removed the hearts’ cells. This left only the frames of the hearts. These heart frames were hooked up to machines in a laboratory.Scientists created a mixture of living heart cells from very young rats. The scientists then pumped this mixture into the heart frames. Next, they ran a special liquid through the parts of the frame that lined the heart’s blood vessels. The liquid’s job was to imitate blood flow. Finally, scientists jump-started the hearts with electricity.After a few days, the hearts began to beat on their own. Taylor said that the team could see the tiny heartbeats using a microscope. The heartbeats grew stronger. By seven or eight days, the heartbeats could be seen without a microscope.Now, scientists want to see if the experiment will work on a larger animal. They plan to soon try the experiment on a pig.”We have a long way to go,” Dr. Taylor said. But she hopes to someday build a working heart for humans.The idea of building new human hearts from the heart cells of anima

ls is exciting. It could be helpful for people who are ill. Experiments with cells have led to many new discoveries.The cell is the smallest unit of a living thing. Some organisms are made of just one cell. These organisms are unicellular. They are usually too small for you to see. Other organisms are made up of many cells. Most of the organisms you can see are like this. Take frogs and water lilies, for example. These organisms are made up of many cells. Organisms made up of many cells are called multicellular organisms.Frogs and water lilies are both examples of multicellular organisms. Their bodies are more complex than unicellular organisms. They have many cells. These cells work together. They carry out the basic activities of life. Different parts perform different functions. A frog moves with its arms and legs. The animal eats with its mouth. Think about a water lily. Its roots hold it in the soil. The plant’s leaves take in energy from the Sun. Tiny unicellular organisms also live in the pond water. They too, perform all the activities that characterize life.Most cells are microscopic. They are too small to see without a microscope. Using a microscope, scientists have studied cells and gathered facts. Three ideas about cells became so important that they were grouped together. This group of ideas came to be called the cell theory. Scientists summarize these three main concepts. Read each one. Then, see how it relates to a polar bear.Every living thing is made up of one or more cells. (A polar bear is a multicellular organism.)Cells carry out the functions needed to support life. (Polar bears have fat cells. Fat cells give the bear energy. They also help keep the bear from getting cold.)Cells come only from other living cells. (Each polar bear began as just one cell.)The question:-You read about an investigation. Researchers want to make new hearts from the cells of rat hearts. Tell about the investigation. Researchers think the data could be helpful to human health.Explain why they think this. Give facts from the readings in your answer.
