internal organs of human body and their functions:




Internal Organs


  • The largest internal organ is the small intestine.
  • Despite being called the smaller of the two intestines your small intestine is actually four times as long as the average adult is tall. If it weren't looped back and forth upon itself it wouldn't fit inside the abdominal cavity.



  • The human heart creates enough pressure to squirt blood 30 feet
  • No wonder you can feel your heart beat so easily . Pumping blood through your body quickly and efficiently in the strong contractions of the heart and the thick walls of the ventricles which push blood to the body



  • The acid in your stomach is strong enough to dissolve razor blades .
  •  While you certainly shouldn't test the fortitude of your stomach by eating a razor blade or any other metal object for that matter , the acids that digest the food you eat aren't to be taken lightly . Hydrocholoric acid the type found in your stomach is not only good at dissolving the pizza  you had for dinner but can also eat through many types of metal



  • The human body is estimated to have 60,000 miles of blood vessels .
  •  To put that in perspective the distance around the earth is about 25000 miles making the distance your blood vessels could travel if laid end to end more than two times around the earth.





  • You get a new stomach lining every three to four days . The mucus-like cells lining the walls of the stomach would soon dissolve due to the strong digestive acid takes it toll o the lining of your stomach.




  • The surface area of a human lung is equal to a tennis court . In order to more to more efficiently oxygenate the blood the lungs are filled with thousands if branching bronchi snd tiny grape-like alveoli . These are filled with microscopic capillaries which oxygen and carbon dioxide . The large amount of surface area makes it easier for this exchange to take place and makes sure you stay properly oxygenated  at all times .



  • Women's heart beat faster than men's .
  • The main reason for this is simply  that on average women tend to be smaller than men and have less mass to pump blood to. But women's and men's hearts can actually act quit differently , especially when experiencing taruma like a heart attack and many treatments that work for men must be adjusted or changed entirely to work for women.




  • Scientists have counted over 500 different liver functions.
  • You may not think much about your liver except after a long night of drinking but the liver is one of the body's hardest working largest and busiest organs . Some of the functions your liver performs are ;production  of bile decomposition of red blood cells plasma protein systhesis and detoxification.



  • Your left lung is smaller than your right lung to make room for your heart
  • For most people , if they were asked to draw a picture of what the lungs look like they would draw both  looking roughly the same size. While lungs are fairly similar in size, the human heart  though located fairly centrally is  tilled slightly to the left making it take up more room on that side of the body and crowding out that poor left lung.




  • You could remove a large part of your internal organs and survive . The human body may appear fragile but it's possible to survive even with the removal of the  stomach the spleen , 75% of the  liver 80% of the intestines, one kidney one lung and virtually every organ from the pelvic and groin area . You might not feel too great but the missing organs wouldn't kill you ..
