Strontium-90, an isotope emitted from nuclear fission, is chemically similar to calcium. This means that when it is inhaled after a nuclear blast, the body uses it as it would use calcium, depositing it straight into your bones where it delivers beta radiation to your bone marrow.
2. Everyone has an Adam’s Apple. The Adam's Apple is thyroid cartilage that acts as a shield for the larynx. It is more prominent in men because men commonly have a larger larynx.
3. Titanium is the most bio-compatible metal, and new bone tissue will bond with it at the atomic level.
4. Gastrocolic reflex is what makes you want to poop after a meal, as your body senses stomach stretching and digestion as a cue to ramp up colon activity and make room for more food.
5. Before the invention of the heart-lung machine, surgeons used “cross circulation” for open heart surgeries. A child was connected to their parent’s heart, which oxygenated the patient’s blood and pumped it back in.
Tall, thin males are at a much higher risk of spontaneous pneumothorax or sudden collapse of a lung.
7. Sword swallowing is not an illusion of any kind: the performer actually pushes the sword down their oesophagus and into their stomach. 29 deaths resulting from sword swallowing have been reported since 1880.
8. After examining skeletal remains of medieval men, archeologists can tell who were archers because bows required a lot of strength to pull which deformed bones.
9. There is a highway in Russia known as the Road of Bones, as the skeletons of the forced laborers who died during its construction were used in much of its foundations.
10. Black Death resulted in a stronger and longer-living human population. Scientists examined the bones of those who died before and after the plague and determined that people who were born after were stronger and more fit.
Drowning in salt water is different than drowning in freshwater. It takes longer, and salt water draws blood from the cells into the lungs. You drown in your own blood.
12. It's possible to be declared brain-dead falsely because most physicians look at the brain stem, which controls heart and lung functions, but not the cortex, which coordinates consciousness.
13. Fracture Putty is a material that is being developed that when packed in and around a bone fracture, provides full load bearing strength within days. It would create an osteoconductive bone-like structure that degrades into harmless resorbable byproducts as normal bone heals.
14. Humans are the only primates without a penis bone, leaving us dependent on hydraulic pressure alone. The penis bone in other primates “aids sexual reproduction by maintaining sufficient stiffness during sexual penetration.”
15. The Japanese word for “Uvula” (the dangly thing in the back of your throat) is “Nodo Chinko” (ノドチンコ), which directly translates to “Throat Penis.”
16Hole in the heart
When you are born and take your first breath, the pressure change in your lungs causes a valve between the two atria in your heart to close and eventually fuse. When this doesn’t happen correctly a baby can have a hole in their heart, but initially everyone had the same hole.
17. Laser tattoo removal is the process of using different wave lengths of light to break down the metallic ink particles to sizes small enough that they can be passed to the liver by your body’s white blood cells.
18. We typically do not start to think of foods as “too sweet” until our bone growth stops. Younger children have virtually no limit to the amount of sugar they find palatable.
19. Babies can drink and breathe at the same time, even though adults can’t. For the first 3 months of life their larynx acts like a little snorkel.
20. Common vaccines used on “hundreds of millions of people” were developed from lung tissue cells of a 3-month-old female human fetus aborted in Sweden in 1962. It’s not clear if the mother gave her permission.
The first-known definitive case of a benign bone tumor was discovered in the rib of a 120,000 year old specimen of a young Neanderthal.
22. Corexit, the chemical dispersant used to “clean” the BP oil spill, is known to have high levels of toxicity in humans, with known links to lung damage, cancer, and other chemical poisoning effects. Corexit is still the go-to chemical for oil spills with no policies banning it in the US.
23. Tonsils are strategically placed near the airway in order to “catch” incoming bacteria and viruses. They often become infected as their main purpose is to sample these bodies and build up immunity so that the much more vulnerable lungs are able to fight off infection.
24. The fertilizer used by the Tobacco Industry is radioactive. The plant absorbs it and the smoker inhales it. It gets lodged in the lungs and over time contributes a huge radiation dose to the smoker and could be a factor in lung cancer.
25. You can’t breathe while pooping because your epiglottis closes and you use the air pressure in your lung to push out the waste.
