since it is the hearts job to pump blood throughout the body of an organism, the circulatory system would fail and the entire organism would suffer if the heart cells stopped working properly.
High blood pressure can lead to stroke, loss of vision, heart failure, heart attack, kidney disease, and reduced sexual function. A stroke can happen when one of the vessels that lead to the brain either becomes blocked by a blood clot or bursts. This stops blood flow and prevents oxygen from getting to the brain.
