How do You Strengthen a Weak Heart?

The heart is one of the most important parts of the body. It is an organ but is considered to be a muscular organ because not only is it comprised of different types of tissues and cells; it is also largely made of a type of muscle tissue called the cardiac muscle. The heart’s primary function is to pump blood throughout the body. This blood supplies oxygen and nutrients to the tissues throughout the body and removes carbon dioxide and other waste.
