Largest Body Organ

Largest Body Organ - Skin
As you think about all of the organs in your body and how important they are, don’t forget the largest body organ. It’s also the one that is most visible—your skin.

Have you ever considered how incredible your skin is? The hands of a laborer may be rough like sandpaper, but his abdominal skin could be smooth and soft. The calves of your legs have skin bonded tightly to a muscle layer. The skin on your elbow can be lifted loosely in rolls. If you used a microscope to examine the skin of our scalp, lip, heel, and finger, you might think you were studying sample from different species.

Your skin is the largest body organ, and there is no other organ like it. It flexes, folds, stretches, and bends around joints. It’s sensitive to touch. The skin of your finger pads is sensitive enough to detect a grain of dust on a smooth surface or read Braille letters in a book. When you blush (something that only humans do), the blood vessels of your skin suddenly rush many times more blood than usual. Your skin even regenerates itself when it’s damaged.

Your skin shows emotions, cools and insulates your body, protects you from germs, serves as a receptor for all kinds of stimuli, and gives you that unique appearance. We often cut off the hair growing out of our skin or add some substance to soften and beautify our skin. We seldom take a moment to realize what a fantastic organ it is.

Of all the vital organs of your body, your skin is the most visible. Skin color or texture may vary from person to person, but regardless of those factors, it protects what is inside. Your largest body organ is another incredible design by a Master Designer.

Multi-purpose Robot Design

Multi-purpose Robot Design
The versatility of the human body is truly amazing. Think of all the things that humans can do. We can walk, jump, climb, and run. We can lift, throw, catch, and push. Our fingers, hands, arms, and legs can do many wonderful things. They can even do multiple different kinds of things, sometimes at the same time. Consider all of the things your mouth can do. You use your mouth to talk, sing, eat, drink, blow, kiss, and smile. Robot designers have not been able to create a robot that can do everything the human body can do. Perhaps taking a cue from the “Transformers” movies, some engineers want to develop a multi-purpose robot design.

The job is not easy. Some are experimenting with the idea of creating heat-activated origami suits that serve as exoskeletons for a robot to allow it to do different tasks. The robot would change costumes to “transform” itself. Just as crawling caterpillars morph into flying butterflies, the goal is to create a robot that transforms itself by taking on a different form as it applies a different suit. The director of the project at MIT’s Computer Science and Artificial Intelligence Laboratory said, “With this metamorphosis-inspired approach, we can extend the capabilities of a single robot by giving it different accessories to use in different situations.”

It sounds like a very challenging task to create a self-morphing robot. However, changing an outer shell to give the robot different functions is not the same as the metamorphosis of a caterpillar. In a way that is beyond robot engineering, the caterpillar dissolves into mush then reorganizes into something completely different. It doesn’t merely take on a new shell. This worm with no real brain does something that the brightest engineering designers can’t accomplish.

Getting back to the versatility of the human body, that has to be the most significant engineering accomplishment ever. We can do a countless number of different things. Then using the brain that God gave us, we can create tools (even robots) to accomplish the tasks we don’t have the strength or stamina to do. Multi-purpose robot design is a worthy challenge requiring the versatile abilities that only God could give us.

The Human Body and the Christian

Human Body

One of the unique teachings of the Bible is that the human body is the temple of God. First Corinthians 3:16 says it clearly: “Don’t you know that you are the temple of God, and that the Spirit of God dwells within you?” This concept is repeated numerous times throughout the New Testament. The consequences of that belief are very significant. The next verse tells us: “If any man defiles the temple of God, he will be destroyed: for the temple of God is holy, and that temple is you.”

As Christians, we should treat our bodies with respect and care. Taking recreational drugs of any kind is an affront to that care. The consequences of taking alcohol, nicotine, meth, or crack into our bodies or abusing prescription drugs will ultimately destroy our health. The list of ailments from alcohol and nicotine is massive and growing.

In today’s world, many have been told that vaping involves no health risks. That is simply not true. It is true that e-cigarettes contain no tobacco, but medical data is showing that the vapor from e-cigarettes reduces the body’s ability to heal wounds. Teens who vape can develop smoker’s cough and bloody sores. Chemical analysis shows that the vapors contain cancer-causing chemicals. A new vaping behavior called “dripping” intensifies the effects of vaping and increases the risks.

The human body is an amazing machine, but it is also more than that. God has called us to care for our bodies and to treat them as a sacred dwelling for His Spirit. Involvement in solving the problems facing humanity today is a better high than vaping can ever produce. We cause many of our physical problems by not caring for God’s Temple, and the teachings of Christ should lead us to correct that.
