Healthy hearts are necessary for healthy lives.
Many people are helth-minded these days, and concerned with keeping their hearts healthy.
A strong heart is a hollow muscular organ of vertebrate animals that by its rythumic
contraction acts as a force pump maintaining circulation of the blood.
Heart attacks are very unhealthy, as are myocardial infarctions.
One complete pulsation of the heart is called a heartbeat.
A heart failure is a condition in which the heart is unable to pump blood at an adequate rate,
which can quickly lead to death. Where there's smoke, there is danger of heart disease.
