Love at first sight. True love. Forever love. Always. With all my heart. Real love.
Yes, it is that time of the holiday season again. Saint Valentine’s Day, or Valentine’s Day as we typically call it. It’s traditionally a day when you profess your unfailing love for someone through flowers, candy, cards, or romantic dates, all known as “valentines.” Modern Valentine’s Day symbols include Cupid, doves, and anything heart-shaped.
However, as we all know, there are no feelings of love abounding in the heart organ itself. But have you ever stopped to think of all the amazing things we need our heart for? Not so much for feelings, but actual living.
Today I thought I would give you seven little-known facts about the heart to use with your students.
Did you know:
1) The human heart creates enough pressure when pumping blood out to the body that the blood can squirt 30 feet?
2) On average, a million barrels worth of blood is pumped through the heart in a lifetime?
3) Your heart, made up of mostly muscle, is strong enough to lift approximately 3,000 pounds, the weight of a small compact car?
4) Your heart beats 100,000 times a day, which is enough to fill 8,800 quart-size milk cartons?
5) Your heart does enough work to lift your body 1 mile up into the air?
6) For its size, the human heart is considered one of the world’s strongest pumps?
7) Your heart is able to propel a blood cell completely through your body in just 60 seconds?
When God designed the human heart, He not only made sure it was functional to meet all our bodily needs, but He also made it one amazing organ, leaving no question about random design. Now THAT’s what I call love!
Hmm, well, if the heart is perfect the designer should be sent back to school because it sure isn’t perfect. If god created the heart he, she, it deserves a D if not an F. No I guess a D because it does work. It just could work a lot better.
Given the desire to save lives, reduce grief, and enhance circulation, many doctors would agree to redo a number of heart design flaws.
Heart valves tend to be produced inconsistently such that many people have heart valve problems. Congenital heart valve disease usually involves pulmonary or aortic valves that don’t form properly. These valves may not have enough tissue flaps, they may be the wrong size or shape, or they may lack an opening through which blood can flow properly. Better genetics would eliminate these quality control issues.
Sadly there is no heart-based heart valve monitoring system to detect backflow or faulty valves. People can have heart valve problems for years and not know it, though it affects their health. The heart valve design is too prone to congenital defects.
The heart is unable to detect plaque buildup or to remove plaque. Heart disease is the number one killer now. While it is often diet, it is also an inherent problem within the circulatory system. One which if overcome would extend our life tremendously.
Because we are mammals, our lungs do not function in the fetus, causing the undesirable mixing of oxygenated and unoxygenated blood. This happens in the fetus where there is a hole between the chambers of the heart that must close off at birth. This leads to a relatively common baby condition, the so called “hole in the heart” baby.
If the umbilical cord were inserted at the chest instead of the belly, the umbilical vein and artery could connect directly to the mother’s pulmonary vein and artery, eliminating the need for a hole in the chamber, and providing better oxygenated blood to the baby. This would solve several other problems as well, including the need for a placenta and menstruation!
The hemoglobin in blood has more affinity for carbon monoxide than oxygen. We could relieve some of the work of the lungs and liver, if it were not iron based, and did not prefer attaching to the poison CO.
When a person has congestive heart disease, the heart gets bigger and bigger to compensate. Since the heart doesn’t have a monitor for this, people don’t know they have this problem until it is too late and very difficult to correct.
Since the heart doesn’t have a means of monitoring blood pressure, people suffer tremendously from the silent killer stroke. Many, many lives would be saved if the heart could tell us when it is experiencing too much pressure. Other problems would be eliminated if it could detect too little pressure.
The heart has a hard time coordinating valve opening and closing with chamber contraction, resulting in the common ailment arrhythmia. A better electric circuit in the heart’s atrioventricular node would eliminate this problem.
Black women have a much higher risk of birth-related heart problems, especially, peripartum cardiomyopathy. 93% of people who get this problem are black. A better designed heart would not be afflicted by race issues.
Beneficial bacteria in the gut break down fats so well they more easily deposit on arterial cell walls exacerbating thickening and hardening of the arteries. The heart is unable to combat this. Nor is it able to combat the inflammation from other bacteria in the body (in particular periodontal disease bacteria). We have no consciousness of the need to brush our teeth and not eat so many fatty foods, resulting in diseases we could have avoided.
There is no reason the heart has to have a four-chamber design with a heartbeat. More efficient pumps of more simple design could reduce wear and tear on the heart and the circulatory system. While issues of tissue rejection are more difficult to overcome, the mechanics of pump design are easily met by human heart design.
