“Your muscular heart, the main organ in your cardiovascular system, is vital for life. Its parts work together to move blood through your body in a coordinated way. It constantly sends oxygen to your cells and takes away waste. Many conditions can affect this organ and keep it from working well. Your heart contains four muscular sections (4 chambers) that briefly hold blood before moving it. Electrical impulses make your heart beat, moving blood through these chambers. Your brain and nervous system direct your heart’s function. Your heart controls the speed of your heart rate and B/P.  The heart is the main organ of your circulatory system, your heart keeps you alive. It pumps blood throughout your body, bringing oxygen to your cells and tissues. Since your heart plays such a vital role, it’s important to take care of it. Conditions that affect your heart are very common, but you have the power to make changes for a stronger heart especially before heart problems occur.  The key is prevention.”
