Understanding blood clots

This week we’ve been learning about different heart and circulatory diseases. Although we’ve separated these conditions in real life, particularly in our bodies, they’re very closely linked. For example, blood clots are a major cause of both heart and circulatory diseases.

Blood clotting is a vital function which your body relies upon to repair wounds. Without it, even a small cut could leave us in danger of bleeding to death! Thanks to blood clotting, a paper cut is a mild annoyance rather than a serious injury!

Blood clots in your blood vessels can be caused by many things. For example a build-up of fatty material which narrows the vessels and stops blood flowing properly. In arteries that supply the heart, a blood clot can cause a heart attack. In arteries that supply the brain, a blood clot can cause a stroke.
