Artificial organs are man-made devices designed to replace or support the function of natural organs in the human body. They can be used for various purposes, such as improving health, enhancing quality of life, or extending lifespan. Examples include artificial hearts, kidney dialysis machines, and prosthetic limbs. These devices can be created using different materials, including metals, plastics, and biological tissues. Advances in technology, such as 3D printing and biotechnology, have made it possible to develop more effective and compatible artificial organs. Research continues to improve their functionality and integration with the human body.
