Congenital heart disease

Pulmonary heart disease

Rheumatic heart disease

Coronary heart disease-

Causes- Some of the cause of this disease are not enough oxygen rich blood to the heart because of narrowing or blocking of the coronary artery by fatty plaques.

Symptoms- Heart attack

~Death of section of the heart

~Pain or discomfort in chest

~Heart failure


~Sudden death

Treatments- A stent with a deflated balloon is inserted into the artery through a catheter. The balloon is inflated expanding the stent and widening the artery. Then they take out the balloon and then stent is left in to hold open the artery.

How to keep your circulatory system heathly

~Don't smoke
~Take vitamin E
~Eat fresh vegetables and fruit to provide your body with lots of antioxidants
~Eat fish instead of red meat because it is better for your heart

Fun Facts

~The entire trip around your body only takes blood about 20 seconds in total.
~ If you were able to lay all the veins, arteries, and capillaries in an adult body, end-to-end, they would stretch out over 62,500 miles.
~ Due to the heart having its own electrical impulse, it will continue to beat even when removed from the body as long as it has an adequate supply of oxygen.
~On average, the human body has about 5 liters (almost 9 pints) of blood continually traveling through it. A kitchen sink would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime.
