A Corrosive Stomach Environment

Your stomach acid has a pH of around 2.0. That’s the same pH as hydrochloric acid (HCL). Put a few drops of HCL on your kitchen table and it won’t be long before you have a hole in the table.

The reason our stomachs need that low a pH is beyond the scope of this simple post, but I hope you will wonder WHY that extremely corrosive acidic environment in our stomach doesn’t dissolve our stomach.

 One reason has to do with the mucous cells lining our stomach wall. They serve as a protective coating to prevent that from occurring.

 So, think about this: It is either an astounding bit of luck in the course of our evolutionary development that the mucous cells exist in our stomach . . . .


Or those cells were specifically designed by our Creator to protect the stomach from being dissolved by the acid.

Adam and Eve

As I read through Acts 17 this morning, I stopped at verse 26: “[God] made from one every nation of mankind to live on all the face of the earth . . .” And I got to thinking again about difference between evolution and special creation. The first Man and Woman – as different as the genders are anatomically, physiologically, emotionally, and hormonally – they had to evolve at the same time from whatever it was evolutionists say we evolved. The same time. If not, our species would never have propagated itself. On the other hand, if it happened like God said it happened in those first two chapters of Genesis – a special and sudden creation – then we have the explanation of our species. Seems pretty obvious to me.

Exhaling for Life

Carbon dioxide is the natural byproduct of cellular metabolism. As most people know, we inhale oxygen from the air around us and exhale carbon dioxide (CO2). Everyone knows why we need to inhale oxygen, but not many know why it is important to life that we exhale CO2. That’s the focus of today’s post. CO2, when combined with the water in our blood, becomes carbonic acid. As carbonic acid builds up in our blood system, the acidity of our blood increases. But there is a limit as to how much acidity our body can tolerate. A significant increase for too long – an hour or less in many cases – will kill us. One the other hand, too little acidity in our blood for too long will also kill us. Now here is where we are either the product of an extraordinary chain of lucky evolutionary events – or we are the product of an extraordinary intelligent Creator. Near the part of our brainstem called the ‘medulla’ are specialized cells called chemoreceptors. Those cells respond to changes in

Frank Starling and the Heart

This is a very superficial explanation of the Frank-Starling Law (FSL) as it relates to the heart. You can find more information by doing a simple internet search. Not many people have heard of the Frank-Starling Law. Or if they have, they’ve probably forgotten it. That’s too bad, because the Law speaks a lot for sudden and special creation vs. evolutionary change. The FSL recognizes that when certain muscle fibers are stretched, they recoil in proportion to their stretch. Think of a rubber band. Stretch it in you hands a few inches and let it go. It recoils only a little bit. Stretch it as far as you can without breaking it, and it snaps back hard enough to sting your fingers. The FSL depends on an extraordinarily complex interaction of calcium and other electrolytes with specially designed muscle fibers. Without even one of the dozen or so critical elements responsible for muscle fiber recoil, the entire Law falls apart. That is an important point. Cardiac muscle fibe
