It is important to realise that an acre can be measured in any shape - from rectangles to circles or even hexagons - so long as the total area of land is 43,560 square feet. The most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet. If you're struggling to get your head around just how big that area actually is, try visualising 60% of a soccer pitch, 75% of an American football field or 16 tennis courts in a 4x4 formation. If that doesn't help, consider a car park containing 150 cars parked in a square.
Introduction. Aspirin is an antiplatelet medicine, which means it reduces the risk of clots forming in your blood. This reduces your risk of having a stroke or heart attack. Normally, when there is a cut or break in a small blood vessel, a blood clot forms to plug the hole until the blood vessel heals.
Answer Wiki. Aspirin irreversibly inhibits platelet function, which means once aspirin acts on platelets, it prevents them from adhering to each other during their entire life span. The life span of platelets is 7 days, so a platelet on which aspirin acts remains inhibited for its entire life span.
