Heart Disease; The number one Killer in America for the last 90+ years! That is a decade of people dying in the millions from a disease that is easily preventable with a little gem called therapeutic lifestyle change (TLC).
TLC is the idea that a healthy diet and regular cardiovascular exercise can treat and prevent heart disease at rates that are comparable to pharmaceutical medications. Up until recently, we knew that TLC could treat and prevent heart disease, but now we know that it can also REVERSE heart disease! Visit the exercise section of this blog to find out more about heart healthy exercise.
It is no surprise to me that therapeutic lifestyle change shares an acronym with tender love and care, after all changing your lifestyle to a healthy diet and regular exercise is the best type of self love and care there is.
What does the heart do?
It pumps blood to the body for nutrients and energy:
The heart is a vital organ. It is responsible for pumping blood around the body. Oxygen attaches itself to red blood cells in the lugs and then gets dumped into the heart for distribution to the rest of the body. The heart is the center of the Cardiovascular System, an interstate like path of arteries, veins and capillaries that usher oxygen to muscles and organs. It is a powerful muscle that squeezes down to push
The pathway of blood in the heart. “Used” blood is called de-oxygenated blood and usually is depicted in the color blue. Blue blood comes in from the body after it is used by the muscles and is funneled in through the Vena cava into the right side of the heart. It is then pumped into the lungs through the pulmonary arteries (that is where that first “lub” sound comes from). After it is oxygenated in the lungs, it is usually depicted in the color red. Red blood comes back into the left side of the heart from the lungs through the pulmonary veins and then is pushed out to the rest of the body through the biggest artery in the body, the Aorta. The exit of the oxygenated blood into the body makes the second “dub” sound.
How does that happen?
They heart has its own electrical system that creates the impulses responsible for the muscle contractions. The muscle contractions move blood by squeezing it out and through the veins and arteries. The electrical pulse has to be timed perfectly so that the heart chambers can fill with blood to the right volume and then squeeze from the bottom up to push the maximum amount of blood out each time.
I bet you didn’t know that all of that was happening each time your heart beats!
