Why will a blood clot may stop an organ working properly?

A blood clot can obstruct the flow of blood to an organ, depriving it of essential oxygen and nutrients needed for proper function. This interruption can lead to tissue damage or death, impairing the organ's ability to work effectively. In critical cases, such as a clot in the heart or brain, it can result in severe complications, including heart attacks or strokes, further disrupting the body's overall health.
