A chemical equation represents by using these chemical formula of reactants and products molecules. For writing the chemical equation, first write down the formulas of substance involves in reaction, than place a plus sign between chemical formulas of substance with an arrow after last reactant molecule.
[edit on Wikidata] Thrombosis (Greek: Î¸ÏÏÎ¼Î²ÏÏÎ¹Ï) is the formation of a blood clot (thrombus; Greek: Î¸ÏÏÎ¼Î²Î¿Ï) inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss.
A thrombus is a clot that blocks blood flow. If part of the thrombus breaks away, it is called an embolism. Sometimes clots form inside vessels where there is no injury and they do not dissolve naturally. Abnormal clots can form in arteries or veins, important vessels that transport blood around the body. Arteries carry oxygenated blood from the heart to the rest of the body and veins carry deoxygenated blood away from the body's organs and back to the heart.
