- Unborn babies do not need a double circulatory system-hole in the heart usually closes at birth
- Hole in the heart mixes oxygenated and deoxygenate-d blood-arterial blood carries less oxygen
- Donors correct major heart problems
- Heart assist devices-extra pressure, allow damaged muscle to recover
- Rejection from transplants- immuno-suppressing drugs
- Platelets- exposed to the air, complex chemical reactions, mesh of fibrin fibres (clot)
- Agglutination-blood groups are incompatible
- Agglutination in red blood cells react with blood plasma-transfusion endangers life
- Agglutination-blood groups are incompatible
- Damaged/ weak valves-lower blood pressure, blood leaks backwards
