Do you ever think about what it is that keeps your body warm? While there are external influences, the main internal influence is heat energy that is converted from food you eat and is carried to your body’s extremities by your blood. You are called a warm-blooded creature because your blood is warm.
Beneath your soft flesh gushes a pressurized river of heated red blood that is racing through an incredibly intricate plumbing system. Ugh. It’s not really a pleasant thought, unless you are some sort of biological geek that actually enjoyed cutting up dead worms in school.
Like it or not, if you are an adult human being, you contain more than a gallon of blood, which is just over 7 percent of your total body weight. Your heart is an amazing pump made of muscle, slightly larger than your fist. It continuously pumps blood through the circulatory system, beating around 100,000 times and pumping about 2,000 gallons of blood each day. In an average lifetime, the heart beats over 2.5 billion times.
This blood flow is as essential to our body as air is to our lungs. We can’t live without it. The blood works in tandem with our lungs to be oxygenated and then through our fully automated cardiovascular system it carries oxygen and nutrients to every cell of our body. If we lose our life’s blood, the body will shut down and result in our death.
Most of us are alarmed when we see any blood. Intuitive alarm bells go off when we see its red color. We use the color red to paint stop signs, fire alarms, and fire engines because of this reaction.
