CIRULATORY SYSTEM

[] [] [] []

During 16th century, egyptians wrote on the papyrus their own circulatory system by violent experiments. They thought air would go through their mouth and into their lungs to the heart at last. From the heart, the air travelled to all the members in the body by arteries in their papyrus and this is one of the most important scientific thought.

If our circulatory system goes wrong we will have heart and lungs will go wrong. For heart, if the arteries and veins are stucked by fat and can't go into the heart, we will have heart problems such as heart disease. For our lungs, mostly we get asthma by allergy. If anyone is seriously allergic to a thing and if they eat the thing they will have to inject strange fluid to make them save. If they don't inject it will lead to death seriously.
