The Heart Is on the Left, but Why?

The Heart Is on the Left, but Why?

When I was in high school, a required health course involved a plastic model of the human body with the skin removed and all the organs visible. We named the model “Oscar” and tried to change the arrangement of the organs. We learned that correct internal organ placement is essential, and the heart is on the left.

Getting all the organs into Oscar was difficult because they were hard plastic, and not all organs are symmetrical. We learned that there were reasons for the human body’s design, and the heart is on the left, but we didn’t know why?

We learned there is a reason for the brain to be at the top of the body to avoid a stroke. The pressure in a column of liquid is greater at the bottom than at the top. For that reason, a blood vessel can rupture in our feet but still not be critical to our survival. If our brain were in the lower part of the body, a broken blood vessel would lead to a stroke.

So what determines where our organs are placed? A recent study led by Harvard Medical School researchers gave some answers to that question. In early embryonic development, a cluster of cells called the left-right organizer contains some hair-like structures called motile cilia. They sense the biomechanical forces that shape the body plan. The cilia beat rapidly, moving extracellular fluid in the correct direction to move organs to the proper place to function most efficiently. They are the reason why the heart is on the left side.

Incorrect left-right placement of the internal organs can result in various disorders, including heterotaxy syndrome and primary ciliary dyskinesia. These disorders can cause recurring respiratory infections and congenital heart disease.

In Psalms 139:10-14, David speaks of God’s right hand forming him in the womb. In verse 14, David says, “I will praise you, God, for I am fearfully and wonderfully made…” The more we learn about how our bodies are designed and formed, the more we understand the truth of that statement.

What Your Body Does in a Day

What Your Body Does in a Day

Own Olbricht sent us this summary of what your body does in a day. We thought it was worth considering the fantastic abilities of the bodies God has given us.

*Every day your heart pumps approximately 2,000 gallons of blood through its chambers.
*On average, your lungs take in 17,000 breaths a day with a typical lung capacity of roughly six quarts of air.
*Your brain processes over 50,000 thoughts a day – 35-48 thoughts per minute.
*Your stomach lining has cells which produce an alkaline substance every few milliseconds to neutralize stomach acid. The stomach would dissolve itself without its lining.
*Your eyes blink 28,000 times a day, with each blink lasting 1/10th of a second.
*Your body’s energy system expels enough heat to light twenty-five 100-watt light bulbs every day.
*Your skin is the largest organ of your body, and you shed a million skin cells every day.
*Your hair grows a millimeter a day. The average adult’s full head of hair consists of 100,000 strands.
*Your liver filters 1.53 quarts of blood every minute, and every day it produces a quart of bile to help digest food.
*Glands in your mouth produce more than a quart of saliva every day.
*Every minute your kidneys filter 2.2 pints of blood or 3168 pints per day. They expel 2.5 pints of urine every day.
*The average person will eat over 50 tons of food in a lifetime.

What your body does in a day is an excellent testimony to God’s wisdom, intelligence, power, and design.

Your Heart Is More than a Muscle

Your Heart Is More than a MuscleI recently had some concerns about my heart, which turned out to be unfounded. In the process of various tests, one of my atheist friends said to me, “Well, after all, your heart is just a muscle, but I guess you religious guys don’t believe that, do you?” My response was, “Well, you don’t either!” Your heart is more than a muscle.

All of us know that the physical heart beating inside our chest is a muscle. It is probably the most studied muscle in the body. I was fascinated as I watched my heartbeat in the echocardiogram. I was amazed to have the heart specialist point out the valves and the design of the vascular system that feeds blood throughout my body. It was also interesting that I could change the rate of my heartbeat, and in turn, my blood pressure, by thinking about certain things. The technician doing my echocardiogram said, “Oh yes, there’s a lot more to the heart than the muscle.”

In the Bible, the word “heart” has many uses. In the Old Testament, the Hebrew word for “heart” occurs 29 times referring to the physical organ directly or figuratively. (See 1 Samuel 25:37, 2 Samuel 18:14, 2 Kings 9:24.) Old Testament writers use the word 257 times to refer to personality, inner life, or character. (See Exodus 9:14, 1 Samuel 16:7, Genesis 20:5.) An additional 166 times it refers to emotional states of consciousness. Some examples are: intoxication (1 Samuel 25:36), joy or sorrow (Judges 18:20, 1 Samuel 1:8), anxiety (1 Samuel 4:13), courage and fear (Genesis 42:28), and love 2 Samuel 14:1). Also 204 times it refers to intellectual activities such as attention (Exodus 7:23), reflection (Deuteronomy 7:17), memory (Deuteronomy 4:9), understanding (1 Kings 3:9), or technical skill (Exodus 28:3).

Finally, 195 times it refers to volition or purpose (1 Samuel 2:35). This varied use continues in the New Testament with the most common application referring to our mind. (See Mark 12:30-33.) Your heart is more than a muscle.

The point is that the word “heart” is used frequently referring to something that is the center of things and rarely does it refer to the physical heart that beats within our chest. God calls us to put Him and His Word at the center of our lives. Jesus said, “Blessed are the pure in heart: for they shall see God” (Matthew 5:8). Paul wrote that when “Christ dwells in our hearts by faith,” we can comprehend the love of God (Ephesians 3:17-19). In that sense, it is true that your heart is more than a muscle.

Dinosaur Blood Pressure

Dinosaur Blood Pressure in BarosaurusIt’s an animal that does not exist on Earth today and which poses some serious challenges to a chance explanations. It’s a dinosaur called the barosaurus. Skeletal remains of this animal show that its head would have towered fifty feet (more than 15 m) above the ground. We have seen drawings of these huge herbivorous dinosaurs. Many of us have seen the reconstructions based on the bones such as the one shown in the American Museum of Natural History in New York. No one denies the size of the animal. The problems come when we start looking at its anatomy. The problem of dinosaur blood pressure raises some serious questions.

The animal with the longest neck today is the giraffe. To get blood to its brain, a giraffe has a systolic blood pressure as high as 350. Systolic pressure is the pressure produced when the heart contracts. For humans, anything over 140 is considered high. To create that much pressure, the weight of the giraffe’s heart weighs is about 25 pounds (11.3 kg). A human heart weighs about 11 ounces (310 grams). For a barosaurus, the heart would have to weigh tons. Also, the blood vessels would have to be extraordinarily thick. It is difficult, if not impossible, to believe that such conditions could exist.

Years ago, two scientists working at the investigative Cardiology Laboratory at St. Luke’s Roosevelt Hospital Center in New York developed a proposal that barosaurus had eight hearts. They suggested a heart like ours pumped blood from the body to the lungs and back. They then suggested a complicated series of seven other hearts. Their idea was that there would be a single-chamber secondary heart above the primary one. It would have one-way valves to boost the blood into the neck. Above the second heart, the artery would divide into two branches sending blood to the brain. Three hearts along each branching artery would pump the blood to the next heart until it reached the brain. This arrangement would reduce the dinosaur blood pressure so that the systolic pressure would max out at about 180.

This is a theory which in all probability will always remain as just another imaginative proposal. It is doubtful that there will ever be any way to test it. The point is that the anatomical complexity and the number of critical parameters required would make this dinosaur blood pressure system virtually impossible to happen by chance. Each heart’s pressure would have to be critically adjusted to just enough to move the blood to the next level. If the dinosaur blood pressure were too high, it would damage the delicate valves of the next heart. What would happen when the animal ran? Each heart would have to speed up, but not at the same rate.

We suggest that proposals like this defy any possible accidental cause. If a person wants to accept chance as a faith proposition in spite of its inadequacies, they are certainly free to do so. But the more variables that must be controlled to achieve the desired effect, the less likely it is that the result can be a product of chance. They can better be explained by design.

Anatomical Bible Words (Part 1)

Anatomical Bible Words
One of the most ambiguous words used by believers and atheists alike is when they say they are taking the Bible “literally.” It is ambiguous because of the underlying assumptions people make about the biblical translations. Word meanings can change over centuries and sometimes over decades. We can think of words, such as “gay,” which have changed in meaning in our lifetimes. Sometimes believers get confused by the meaning of Bible words in the King James Version. Skeptics especially like to criticize anatomical Bible words for being inaccurate.

At one extreme, some Bible fundamentalists insist that the King James Version was given by direct revelation from God to the translators in 1611, and that it is 100% correct. There are massive difficulties with that view. There are both translation mistakes and antiquated vocabulary in the KJV. Many words used in the KJV have gone out of use or have different meanings today.

A translation error we have mentioned before is in Genesis 6 where nephilim is translated “giant.” That mistranslation was a carryover from the earlier Latin Vulgate translation. In the Vulgate, the Latin scholars translated nephilim as gigantus which means “giant.” The KJV translators didn’t go back to the true meaning of the word nephilim which is “fallen ones.” The Hebrew word nephilim is derived from naphal which means to fall, fall away, or be cast down.

At the other extreme, atheists, skeptics, and biblical minimalists have claimed that the Bible is full of errors. They say that anatomical Bible words show a lack of understanding of basic science. The Hebrew word for kidneys is kelayot and it was used by the ancients in the sense of “mind” or “interior self.” We find it used eleven times in the Old Testament in reference to humans. In the KJV it is usually translated “reins.” We all know that the kidneys filter our blood and remove wastes, but the Bible never identifies the kidneys with that function. In Job 19:27 kelayot is translated “heart” or “mind” in most translations. In Proverbs 23:16 most translations read “innermost being.”

So does this mean that the Bible is not the word of God because our creator should have understood that kidneys are not the seat of our inner self? We believe that the Bible is the inspired word of God. We have stated before that we must understand the Bible literally. To take it literally means to look at who wrote the passage, to whom it was written, why it was written, and how the people of the day in which it was written would have understood it.

The biblical passages we have referred to were written to common people in an ancient time in words that they could understand. If they could not understand it, they would never have passed it on to us. Our knowledge of human anatomy is far beyond that of the ancients. We can understand what the Bible is saying and so could those who lived in ancient times. The Bible is God’s word for all time, not just today. We will continue with more on anatomical Bible words tomorrow.
