Artificial materials. The artificial materials are those elements that are manufactured by humans from natural materials. With this type of materials goods and final products are made that are purchased by consumers. These goods can be made up of a single material, such as a glass, or more than one, such as a house.

A total artificial heart is a pump that is placed in the chest to replace damaged heart ventricles and valves. Ventricles are the chambers of the heart that pump blood to the lungs and other parts of the body. The total artificial heart has ventricles made from polyurethane, a widely used artificial material that is both durable and flexible.
