World Thrombosis Day
Celebrated on 13 OctoberProblems with blood clotting lead to blockage of blood vessels.
Blood clots forming in problem areas prevent the free circulation of oxygen and contribute to the accumulation of metabolic products, including lactic acid. Blockage of blood vessels is the main cause of strokes and myocardial infarctions. The success of treatment and prevention of deadly diseases depends on people's awareness of the causes of their occurrence and the characteristics of their development.
