cause tiny particles in your blood (known as platelets) to stick together to form a blood clot. By inhibiting prostaglandin production, aspirin
slows down clot production. Although this can be bad, such as with a bloody nose -- in which case you want a clot to form -- blood clots
can be damaging as well, such as in causing heart attacks by clogging the blood vessels that bring oxygen
and energy to the beating heart.
