Circulatory Lesson #1

"Emotions can affect the human heart, but they do not control it."

As I sit in Human Bio, this statement leaps out at me. This lesson is true, the SA node allows for atrial contraction. Valves allow blood to flow into the proper chambers. Oxygenated blood is sent to vitalize the rest of the body, for all body systems are interconnected. The miracle that occurs in the heart is thus felt throughout the entire being. The gears of a tiny Music Box have the ability to create a light whimsical tune. Yes, that melody is the product, the music, the very element for which the Music Box has been named for, but at the end of the day it’s those gears that hold all responsibility. How comforting to know that blood flows, no matter where the heart figuratively goes. There’s a science to everything.
