Imagine you’re standing on the 10 yard line of a football field. It’s a beautiful day and you take in a deeeeep breath of fresh air….
AHHHHHCHOOOOOOO! At a rate of 90 miles per hour, your body has just expelled foreign particles or irritants and has cleansed your nasal cavity within seconds of you taking in fresh air! Your body has literally expelled those irritants 43 yards, more than halfway down the field!
The oxygen that you just inhaled travels down into the lungs. Blood circulates through and picks up the oxygen, turning bright red in color. The body’s delivery system is in full effect. Red blood cells act as UPS or FedEx personnel, dropping off the precious cargo of oxygen and nutrients and picking up waste products to and from the cells throughout the body.
You decide you are going to do some running on the field! Your body likes the nice internal temperature of 98.6 degrees. As you continue to exercise, your body’s temperature rises. The elevated temperature is being monitored by the brain, and the brain signals the body to perspire, releasing the extra heat, and keeping the body within a nice range of its normal 98.6 degrees.
As you’re running, a friend throws a football towards you! Your eye is on the ball as you run towards the ball to catch it, and ….
YOU TRIP and scrape your knee! That scrape, or “hole” in the skin, exposes the blood. But you shouldn’t bleed out! Platelets in the blood are beginning to break down to release a substance into the blood. This substance eventually forms a clot, preventing excessive blood loss.
These are only a small sampling of the complexities of the human body. We were created by the awesome God, who, by the way, made us in His image and in His likeness. One translation of Psalm 139:14 states “Thank you for making me so wonderfully complex! It is amazing to think about. Your workmanship is marvelous” (New English Bible).
The next time you “Achoo!” think about what is really happening and give God thanks and praise for your wonderfully complex body. The human body intricately designed by God- that’s nothing to sneeze at!
