A brief note on the systems of the body and intelligent design

The systems contained within our bodies are so complex, well designed, and interdependent that they could not possibly have evolved. This concise note will look at just six systems to illustrate plus a final rhetorical question, before closing with a vital conclusion.

The circulatory system

What came first, the heart or the blood? The heart needs to pump blood around the body and does so through arteries, veins and capillaries that needed to have been there for the heart to pump blood and it needs to do so in the right direction. Meanwhile it requires other body systems to function properly to enable it to carry hormones and nutrients to cells and carry away waste products. These needed to have been assembled simultaneously. Some have had a heart transplant which is impressive, but not nearly as impressive as the design of the heart and the circulatory system in the first place.

The respiratory system

What came first, the heart or the lungs? What use is a heart without lungs and a set of lungs without a heart? Did lungs evolve to exchange the correct amount of oxygen and carbon dioxide? Think about it for a moment. How can you evolve lungs if you do not have the required and efficient apparatus to breathe in the first place? If the heart and the lungs were assembled simultaneously whilst running out of oxygen, the trachea needed to have been installed remarkably quickly.

The skeletal system

What came first, the heart, lungs, or the skeletal system? How uncomfortable and painful it is to break one bone. How many attempts would it take to fit over two hundred bones in exactly the correct place? How far can you travel without the skeletal system and how effective would you have been at catching prey or collecting fodder?

The muscular system

What came first, the heart, lungs, bones, or muscles? How long would you need to work out for to strengthen your muscles to survive whilst the rest of your bodily systems are being assembled? How long would it take to attach all the muscles to the bones and what came first the bones, muscles, tendons, or ligaments? It would require an extremely competent team of surgeons and engineers who had already evolved to connect the muscles to the bones without losing too much blood whilst maintaining a steady air flow.

The excretory system

What came first, the kidney, or the bladder, or the digestive system or the excretory system? Constipation is seriously uncomfortable but is nothing compared with the absence of an excretory system. If the other systems had evolved perfectly and simultaneously how can a human survive without a digestive system and an excretory system?

The nervous system

Try putting these systems in order of when they were assembled: the circulatory system, skeletal system, respiratory system, muscular system, excretory system, or nervous system? Surely the nervous system came first since that contains the brain behind the operations and sends instant messages to other parts of the body to perform actions. How did the nervous system survive when all the other constituent parts were evolving and simultaneously being assembled?

One last rhetorical question. How did the reproductive system evolve?

We were made in God’s image

None of us evolved from simple organisms with cell structures that are ‘simple’. We are incredibly well designed by God and since we are made in His image, we have value, life is precious, and we should number our days. None of us is here by accident since we are fearfully and wonderfully made. We are made by God and for God and are created to know God and glorify Him. God’s invisible attributes are clearly seen by the things that are made and we have no excuse.

He has given us life and each breath is a gift, from the Author of Life. God commands everyone to repent because He has appointed a day in which He will judge the world in righteousness, by the Man whom He has ordained. He has given assurance to all by rising Him from the dead (Acts 17:31).
