Anatomy Monday: Cardiovascular System
Poems and Songs tell us we feel with our heart.
We know now that is not true.
But this does not make our hearts any less valuable.
Learn and understand how your Cardiovascular System works.
Protect your body.
We only get one body- there are no upgrades or trade-ins.

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.

Our Beating Heart
There are specialized cells in our hearts that coordinate the muscle contractions of our hearts. They have an intrinsic rhythm that allows them to dictate our hearts’ beating WITHOUT input from the brain. Our brain only gets involved when our heart rate needs to be slowed down or sped up.
The Three Arteries
There are 3 very important arteries that supply each of our hearts. The left anterior descending artery runs down the front of your heart. The right coronary artery runs along the bottom of your heart. And,finally, the circumflex artery runs down the back of your heart

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 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.
