Question 4

Artificial hearts

Answer 4

Artificial hearts are used when a person’s heart stops working completely. It can take a long time for a donor heart to become available, so artificial hearts are used to keep the patient alive in the meantime. There is a risk of blood clotting with artificial hearts. Donor hearts are rarely available and can cause issues with rejection.
