The heart is the organ that pumps blood throughout our body. It's the primary organ of our circulatory system. The heart contains four main sections or chambers which are made of muscle and powered by electrical impulses. The brain and nervous system directs the heart to function properly and efficiently.
How does the heart work?
The heart is part of the body’s circulatory system. It’s made up of the atria, ventricles, valves, and various arteries and veins. The main function of your heart is to keep blood that’s full of oxygen circulating throughout the body. Since the heart is the most crucial organ for our survival, it’s important to keep it healthy. The key to keep the heart healthy for proper functioning is having a balanced diet, regular exercise or some form of physical exertion. Additionally, avoid things that can damage the heart's health for example smoking or excessive drinking.
