Protect your body.

The Importance of the Flow of Blood

Atherosclerosis is the buildup of fats or lipids within the walls of our arteries. One cause of chest pain is when an artery in the heart becomes “clogged” by lipids so that blood cannot adequately flow through it during physical activity. Without proper blood flow, the heart is deprived of oxygen and cannot pump as hard as it would like during exercise.

The FOUR Chambers, The FOUR Jobs

Your heart is made up 0f 4 chambers that have 4 distinct health implications, or jobs: 1)Right atrium collects the venous blood from circulation. 2) Right ventricle pumps the blood to the lungs for oxygenation. 3) Left atrium gathers the oxygen-rich blood from both lungs. And 4) Left ventricle is the STRONGEST chamber of the heart that must pump the blood to the whole body!

Your Heart

Your heart IS a muscle!

It requires energy to keep your blood pumping at all hours of the day, and regular exercise can make that pumping more efficient.
