Today YOU can use biomaterials to fix a broken heart!

The heart is a muscle in the middle of your chest It pumps BLOOD around the full of OXYGEN body and nutrients

There are blood vessels in your body that are called and They connect your heart to all of the parts of your body Each time your heart beats, it pumps blood through your blood vessels to all of the parts of your body

carry blood without oxygen to your heart carry blood with oxygen away from your heart

Heart Facts Your heart beats: • 100,000 times in one day • 35 million times in a year • 2.5 billion times during an average lifetime • How many years would you have to leave the kitchen • tap running to equal the amount of blood your heart pumps during an average lifetime?

Your Pulse Your pulse is blood stopping and starting as it moves • through your arteries 90 to 120 beats per minute for kids • 72 beats per minute for adults • In general, fitter hearts have lower beats •

Coronary arteries supply the heart with blood and carry oxygen and nutrients Coronary arteries in red

Sometimes the can get blocked and blood cannot move through them A heart attack happens when blood cannot move through a coronary Oxygen cannot get to the heart and the heart starts to die Dying heart turns Biomedical Engineers can fix darker colour the heart with biomaterials

Medical devices are made of biomaterials which help the body heal itself

How do WE keep our hearts healthy?

Use blue lines Use red lines on the right on the left side side because because the the blood does blood has not have oxygen oxygen

Feel the same as the heart Stretch with the beats of the heart Be easy for the surgeon to put onto the heart
