artificial pump
2)artificial hearts are mechanical devices that pump blood for a person whose own heart has failed they usually only used as a temporary fix to keep a person alive until a donors heart can be found or to help a person recover by allowing the heart to rest/heal sometimes used as a permeant fix
3)the main advantages of artificial hearts is that they are less likely to be rejected by the body's immune system than a donors heart this is because they are made from metals or plastics so the body doesn't recognise them as foreign and attack in the same way as it does with living tissues
1) if a patient has heart failure doctors may preform a heart transplant using donor organs from people who have recently died however if donor organs arnt available right away or they are not the best option doctors may fit an artificial heart
4) can lead to bleeding and infection they don't work as well as healthy hearts from a donors parts of the heart can wear out like the electric motors doesn't flow as smoothly.

artificial blood
2) artificial blood is a blood substitute used to replace the lost volume of blood its safe and can keep people alive even if they loose 2/3 of their red blood cells
3) ideally an artificial blood product would replace the function of the red blood cells so no need for a blood transfusion
1) when you loose blood your heart pumps the remaining red blood cells around as long as the volume of the blood can be topped up
