“your heart is one of the masterpieces of creation. It is a phenomenal instrument. It has the potential to create vibrations and harmonies that are far beyond the beauty of pianos, strings, or flutes. You can hear an instrument, but you feel your heart. And if you think that you feel an instrument, it’s only because it touched your heart. Your heart is an instrument made of extremely subtle energy that few people come to appreciate.” - The Untethered Soul Michael A. Singer
I didn’t want to separate the organ systems into groups because I didn’t want to give the impression that the systems work independently of each other. This seems like a, ‘No shit Sherlock’ moment, but I didn’t realize this very basic concept until a Human Systems Development class in college. Until that point I believed that the digestive system worked with food. Period. The respiratory system dealt with gas exchange, oxygen and carbon dioxide. Period. And the circulatory system dealt with blood. Period.
I didn’t recognize that the nutrients from the food we eat are carried around in the blood stream to their targets. Or that the organs, ALL of the organs, are made from the food that we eat. That all of the organs are supported by the blood that enriches them with oxygen and nutrients. I also didn’t realize that the lungs needed the contractions of the heart muscle to bring the oxygen around the body in the blood. I thought these gasses floated around inside of us, like the broken down bits of food. They eventually would get to where they were going.
There was this big “Oh!” Moment for me in that freshman class followed by this bit of anger for being taught the systems independently and lead to believe otherwise.
For this, and other reasons, I am not going to separate the Respiratory and Cardiovascular systems. I will attempt to put the pieces together into one category. But please understand that these systems are unified with the other systems to form the perfect being that you are.
