Lesser Known Facts About Ourselves

by Metreye

Eleven systems and five vital organs dwell within us and function in coordination to keep us fit.

Our torso comprises of the head, neck, upper and lower trunk, arms, hands, legs and feet with eleven systems that function in coordination to keep us fit. Five vital organs, namely the brain, heart, liver, lungs and kidneys dwell within us that are necessary for survival. The human body contains nearly 100 trillion cells. There are at least ten times as many bacteria in the human body, as are the cells. An average adult takes over 20,000 breaths a day. Besides this basic information, there is much more that most of us need to know.

Amazing Facts About Ourselves

  • A drop of our blood contains about 10,000 white blood cells and 2,50,000 platelets.
  • For every pound of fat gained, we add seven miles of new blood vessels. This also means that the heart must work harder to pump blood through the new network.
  • Human bone is as strong as granite.
  • According to WebMD, a man's heart weighs about 10 ounces while that of a woman weighs about 8 ounces. The signs that her heart is in trouble are also a lot less obvious. When women have a heart attack they are more likely to suffer from nausea, indigestion, and shoulder aches, rather than chest pain.
  • We tend to burn more calories sleeping than while watching television.
  • The cracking sound made by knuckles, neck, back and other joints when they are cracked, is the sound of bubbles popping in the joint fluid. Though not terribly harmful, cracking a joint too often can hurt the cords called ligaments that surround the joint.
  • Our stomach manufactures a new lining every three days to avoid digesting itself. As part of the digestive process, it secretes a strong acid which the mucous lining of stomach wall keeps within the digestive system.
  • There are more than 600 individual skeletal muscles and 206 bones in our body.
  • It takes an interaction of 72 different muscles when we speak.
  • We are about a centimeter taller in the morning than in the evening.
  • Getting more shut-eye is linked to increased lifespan.
  • Dreaming helps ease painful memories. While we sleep, our brain is still very active repairing connections and producing inexplicable mind movies. Neuroscientist Mathew Walker of UC Berkeley believes that the brain's processing of painful memories enables their emotional sting to be lessened.
  • By the time you are 6 years old, your brain is already 90% of the size it will be when you are an adult.
  • Our nose is our personal air conditioning and purifying system. It warms cold air, cools the  hot air and filters impurities.
  • The sense of smell has a direct effect on emotions. Scent-based memories can be created and stored very early in our lives and retain their power much longer than other types of memories.
