An artificial heart is a mechanical device used to replace a failing natural heart, either temporarily or permanently. It is designed to mimic the function of a healthy heart by pumping blood around the body, maintaining circulation and delivering oxygen and nutrients to tissues. Artificial hearts are often used in patients who are waiting for a heart transplant or who are not suitable for one. They can help extend a patient’s life and improve quality of life by supporting or replacing the heart’s pumping action. Understanding artificial hearts is important in GCSE Biology as it illustrates the ways in which science can intervene in critical health issues.
