the heart has a double circulatory system

^^right^^ pumps ^^deoxygenated^^ blood to the heart

==left== pups ==oxygenated== blood to other organs

the heart has valves to make sure that blood flows in the right direction.

1. blood flows into the %%atria%% %%from the vena cava%% and the %%pulmonary vein%%.
2. the %%atria contract,%% forcing blood into the %%pulmonary artery%% and the %%aorta%% and %%out of the heart%%
3. the blood flows to the %%organs%% through %%arteries%% and %%returns through veins%%
4. cycle %%start again%%

the heart has a pacemaker

your resting heartbeat is controlled by a pacemaker

stent

stents are tubes put inside arteries. they keep them open letting blood pass through to the heart- keeping it pumping.

stents are a way of lowering the risk of a heart attack if you have coronary heart disease
