Who invented the first successful artificial heart?
Explanation: The correct answer is A) Robert Jarvik. Robert Jarvik invented the first successful artificial heart, known as the Jarvik-7, in the late 1970s. His invention paved the way for advancements in the field of artificial organ transplantation.
Which material is commonly used in artificial heart valves?
Explanation: The correct answer is C) Biological tissue. Artificial heart valves commonly use biological tissue, such as animal tissue (e.g., porcine or bovine valves) or human tissue (from donors), to mimic the function of natural heart valves. These tissue valves offer improved biocompatibility and long-term durability.
Which component of an artificial heart helps pump blood?
Explanation: The correct answer is A) Ventricles. The ventricles of an artificial heart are responsible for pumping blood. They mimic the function of the natural heart's ventricles, ensuring the circulation of blood throughout the body.
Which mode of power is commonly used to operate an artificial heart?
Explanation: The correct answer is A) Electricity. Artificial hearts are commonly powered by electricity. External power sources, such as batteries or wall outlets, provide the necessary electrical energy to drive the artificial heart's pumping mechanism.
Which term refers to the surgical procedure for implanting an artificial heart?
Explanation: The correct answer is D) Ventricular assist device implantation. Ventricular assist device (VAD) implantation refers to the surgical procedure for implanting an artificial heart or a mechanical device that assists the natural heart in pumping blood. It is often used as a bridge to heart transplantation or as a long-term therapy for patients with heart failure.
