Scientists reveal new discoveries about the human body almost every day, and some of them sound very surprising to us. We at Bright Side made a collection of facts that suggests there is something really powerful about our bodies.
The acid in our stomach could easily dissolve a razor blade. But, of course, you don’t need to prove that.
- We can live without a stomach, 75% of our liver, one kidney, 80% of our intestines, a spleen, one lung, and any of the organs in the groin area. It’s not gonna be the happiest life ever, but it is possible.
- Our epidermis regenerates every 2-4 weeks. In one year we lose about 0.7 kg of dead skin.
- The bones of an average person can withstand around 16,000 people standing on him.
- The strongest muscle in the body is the masseter — our jaw muscle.
- Without a pinky finger, you would lose around 50% of your hand’s strength.
- Our small intestine is as long as 4 people’s height. It is really surprising how it finds space in our belly.
- Our body contains 60,000 miles of blood vessels.
- The surface area of a human lung is equal to a tennis court.
- Our hair can hold the weight of 2 elephants.
- Our eyes have the ability to change color spontaneously. Most commonly, babies are born with blue eyes, and it takes a certain amount of time for the melanin to be completely deposited to reveal the true eye color. Moreover, the eye pigment depends on the size of the pupil, which changes under certain conditions like emotions or light.
- Humans can survive longer without food than they can without sleep. We can live about 3 weeks without eating, but after 11 days without sleep, our body will start shutting down.
- An average healthy person can produce 4 gallons of sweat during a day.
- We produce enough heat in 30 minutes to boil half a gallon of water.
- During our lifetime, we produce enough saliva to fill 2 swimming pools.
