Vasoconstriction and Platelet Aggregation Defy Evolutionary ExplanationsHoward Glicksman November 6, 2015Hemostasis and the clots it forms must turn on only when it's actually needed and must turn off and stay off when it's not.
Blood Clotting Requires Three Different Processes Working TogetherHoward Glicksman October 26, 2015Think of it like when a pipe in your home bursts. Immediate action is needed.
Blood Flow Requires a Complex, Well-Designed SystemHoward Glicksman October 20, 2015Blood hurtling through the smaller arteries is like automobiles in a crush of rush hour traffic trying to enter the exit ramps to reach their destinations.
Blood Pressure and the Goldilocks PrincipleHoward Glicksman October 16, 2015The numbers have to be "just right," a vital aspect of life that evolutionary biologists never seem to address.
Low Blood Pressure and Evolutionary BiologyHoward Glicksman October 6, 2015What happens when the body can't maintain proper blood pressure?
Blood Pressure: Standing Up to GravityHoward Glicksman October 1, 2015The seemingly simple act of keeping the body upright requires a complex, interrelated system.
Controlling Blood Pressure Requires an Irreducibly Complex SystemHoward Glicksman September 22, 2015Without any one component, the system as a whole would fail and life would be impossible.
The Human Body Continues to Give Evolutionary Biologists High Blood PressureHoward Glicksman September 18, 2015Think of it like the pressure that can be felt as water rushes through a garden hose.
Understanding Cardiovascular Function: Evolutionary Biologists Face a Catch-22Howard Glicksman September 11, 2015Understanding how life came into being requires understanding how the body dies of cardiac arrest.
The Cardiovascular System: Regulating Heart RateHoward Glicksman September 2, 2015To allow for the survival of our earliest ancestors, four different aspects of cardiac function would need to have been working properly.
Cardiovascular Function: Heart Failure Is a Problem for Patients — and for Evolutionary TheoryHoward Glicksman August 28, 2015When the heart cannot meet the metabolic needs of the body it is said to be in heart failure.
Understanding Cardiovascular Function: Real Numbers and Valvular Heart DiseaseHoward Glicksman August 23, 2015Imagine you are trying to get into a saloon through its swinging door.
Understanding Cardiovascular Function: A Challenge to Evolution from Coronary Artery DiseaseHoward Glicksman August 8, 2015If our earliest ancestors could not provide 1,000 mL/min of blood flow to the myocardium, they never could have survived to reproduce.
Cardiovascular Function: What Happens When Real Numbers Are Wrong?Howard Glicksman July 31, 2015As I've noted in previous articles, lung function, hemoglobin production, and cardiac output are controlled by irreducibly complex systems.
Cardiovascular Function Is Irreducibly Complex…But That’s Not AllHoward Glicksman July 22, 2015When it comes to the laws of nature, real numbers have real consequences. Just ask the firefighters trying to put out a three-story blaze.
Understanding Cardiovascular Function: How the Body Controls the HeartHoward Glicksman July 14, 2015Just as a car's performance depends on its engine size and efficiency, so too the body's heart function must meet certain objective parameters.
Cardiovascular Function: The Heart Follows the RulesHoward Glicksman July 9, 2015The body uses the heart to pump blood throughout the cardiovascular system so its cells can get what they need.
Cardiovascular Function: Potassium Control and the Case for Intelligent DesignHoward Glicksman July 2, 2015For the body to survive, the system that controls potassium must inherently "know" what is needed and do it naturally.
Cardiovascular Function: The Body’s Irreducibly Complex System for Controlling Potassium ContentHoward Glicksman June 22, 2015Chance and the laws of nature result in debility and death, not functional ability and life.
Cardiovascular Function: Sodium’s Real Life ConsequencesHoward Glicksman June 16, 2015As Michael Behe would say, the system the body uses to control its sodium is irreducibly complex.
