How The Heart Works
Our Heart the Center of it all
The heart is a large, hollow muscular organ
that pumps blood filled with oxygen and nutrients through the blood
vessels to the body tissues. It is the hardest working muscle in
the entire body.
The average heart beats around 70 beats per minute,
which ends up being over 100,000 beats per day and close to 3 billion
times over the course of an average lifetime.
The heart muscle and blood vessels compose the
cardiovascular system, which is responsible for circulating blood
throughout the body. A healthy cardiovascular system is vital to
supplying the body with oxygen and nutrients.
