Inner structure

  1. Squirting high: The human heart is pumping with enormous pressure, capable of squirting blood up to 9 meters high. No wonder you can feel your heartbeats. It never stops and sends blood against gravity up to the head, and at the same time down to the rest of your body parts.
  2. 100,000km: The length of your blood vessels is about 100,000km. To understand this distance – the circumference of earth is about 40,000km. The distance between the earth the moon is about 300,000km. So if we take the blood vessels of 3 people, and connect them edge to edge – we could easily step where Neil Armstrong did.
  3. Women’s heart beat faster than men’s: The main reason for this is that women’s hearts tends to be a bit small than men’s, but needs to pump the same amount of blood to the body parts, in the same amount of time.
  4. The left lung is smaller than the right: This is to make room for the heart. most people has a heart that tends to lean to the left, which pushes the left lung.
  5. You can live without a significant amount of inner organs: The human body may seem fragile, but it can definitely live without the stomach, the spline, 75% of the liver, 80% of the intestines, one kidney, one lung and any productive organ. It wouldn’t feel so great, and you’ll have to be under medication – but it won’t kill you.
  6. Saliva at 160kph: During a sneeze the spit particles can reach up to 160kph. the sneeze is very dangerous while driving – there is no way of sneezing with your eyes open, which caused a few road accidents already.
  7. Who snores more?: 60% of men and 40% of women up to the age of 60 snore. In most cases a snore can reach 60 decibels. but some people can even reach 80 decibels – same as a concrete drill.

5 Senses

  1. Who will blink first?: Women blink twice as much as men. The average person blinks around 13 times a minute. Blinking is very important to the eye’s health: It helps cover the eye with liquid that has enzymes and Lubricating fluid, that protects it.
  2. The strongest: The outer muscles that moves the eye ball are the strongest muscles in the body, relative to the amount of strength they require: They are stronger 100 times than needed.
  3. Blue, but temporary: Many babies are born with blue eyes, but they wont stay that way for long. The reason for that is the pigment called “Melanin” that sometimes sinks in the eyes cornea after birth. This process require exposure to ultraviolet light, which in the end reveals the child’s real eye color.
  4. Remember 50,000 scents: Our nose can remember 50,000 different smells, many of them are burnt into our memory for many years. but that’s nothing compared to men’s best friend – the dog’s nose is sensitive 1,000,000 times more than ours.
  5. The last to go: The last sense that disconnects while dying is the sense of hearing. The first one being eye vision, followed by taste, smell and touch.
  6. See for a distance: The longest distance that you can gaze into without any help is about 2.4 million light years – 225 trillion kilometers. This is the distance to the Andromeda galaxy, which you can see in bright sky.
  7. Noise sensitive: The smallest noise can make our pupils dilate – this is one of the reasons why surgeons are bothered by noise – dilation of the pupil might cause to be blinded with light , that can cause a disaster.
  8. From birth to old age: Our eyes stay the same size from the moment we are born until we are old age, but the ears and nose does not stop growing. That is why if someone did a nose surgery when he was young – you can see his nose changing over the years.
  9. The strongest organ in our body is the tongue: You may not able to lift weights with it, but relative to it’s size, this is the strongest muscle in body that works almost nonstop by talking, eating and swallowing.
