Imagine you are trying to get into a saloon through its swinging door.
If our earliest ancestors could not provide 1,000 mL/min of blood flow to the myocardium, they never could have survived to reproduce.
As I’ve noted in previous articles, lung function, hemoglobin production, and cardiac output are controlled by irreducibly complex systems.
When it comes to the laws of nature, real numbers have real consequences. Just ask the firefighters trying to put out a three-story blaze.
Just as a car’s performance depends on its engine size and efficiency, so too the body’s heart function must meet certain objective parameters.
The body uses the heart to pump blood throughout the cardiovascular system so its cells can get what they need.
For the body to survive, the system that controls potassium must inherently “know” what is needed and do it naturally.
Chance and the laws of nature result in debility and death, not functional ability and life.
As Michael Behe would say, the system the body uses to control its sodium is irreducibly complex.
Explaining how such a system could arise via an unguided mutation/selection mechanism remains a major stumbling block for modern evolutionary theory.
