20. There are four blood types, namely O, A, B and AB. Nearly half the human population of blood type O. This blood type can donate blood to all types of blood groups, but can only receive type O only. Type the rarest is AB comprised only 4% of the population. People with this blood type can receive all types of blood groups.
21 . In our body , there are about 50-75 trillion cells with around half the red blood cells . Each red blood cell consists of 250,000,000 molecules of iron-containing proteins . Iron molecule is often referred to as hemoglobin . Hemoglobin can transport up to 4 oxygen molecules . Thus, for each red blood cell can send 1 billion molecules of oxygen .
22 . If stretched from end to end , arteries , capillaries , and veins , would stretch about 60,000 miles ( 96,000 km ) at an average child and would stretch about 100,000 miles ( 160,000 km ) in adults . This long enough to circle the earth nearly 4 times a round .

24 . The interior of the human lung is covered by a thin tissue called the 600 million alveoli . Oxygen can pass easily through 1/6.000 inch walls of the alveoli into the capillaries that surround it . When unfolded , the alveoli can cover a tennis court .
25 . Every day , the average adult breathe about 4,250 gallons of air , which consists of 40 billion trillion molecules of oxygen . Along with it there is also a 20 billion particles of dust and other material .
26 . When we cough , the air coming out of our lungs can reach speeds of 600 miles per hour ( 960 km / h ) . This speeds nearing the speed of sound .
27 . Our noses filter and capture more than 70 % of the 20 billion particles of dust that we breathe every day . It also affects the temperature of the incoming air , which is about 77-95 Fo and regulate humidity of 35-80 % .
28 . Every year , people living in the United States attacked nearly 1 billion types of flu . This means , every person stricken with 6 types of flu per year . The reason is , because there are 110 different rhinoviruses that cause the common cold and are 90 other kinds of flu caused by a virus .
29 . Fastest sneeze ever recorded reaching speeds of 100 miles per hour ( 160km / h ) .

31 . The tongue has 10,000 taste buds , but can only detect 4 taste sensations , sweet, sour , bitter and salty .
32 . The small intestine is actually the longest part of the digestive system , which stretches about 22 feet . Large intestine only has a length of 5 feet .
33 . When full , the stomach can accommodate 1-1.5 quarts of food and fluids . It takes 4 hours to digest food and pass into the small intestine in just 2 hours with a speed of 0,002 miles per hour . In the large intestine , the digestive process takes about 14 hours with a speed of 0.00007 miles per hour .
34 . In the small intestine , part of the duty absorption of proteins , sugars and fats from food covered by a layer of small feather-like projections called villi and microvilli . The feathers are able to enlarge the surface area of the gut as much as 600 times than if the surface is smooth . If the small intestine smooth surface , it is necessary to gut the 2.25- mile length to produce the same food absorption by the small intestine that is only 22 feet .
35 . Every day , there are about 3 gallons of food , liquids and digestive fluids through the gastrointestinal tract . Only half a cup only comes out as feces .
36 . Largest muscle of the body is the gluteus maximus/butt . The weight of each piece of ass we are 2 pounds ( not including the fat layer ) . While the smallest is the stapedius muscle that is located in the middle ear , the length is only 1/5 inch .
37 . Most cells in our bodies are so small . However , muscle cells , also called muscle tissue , reaching 1 foot in length and can be seen with the naked eye .
38 . Overall brain weight only 3 pounds can consume 25 % of all energy used by the body . The brain just eat up 2 % of our total body weight .
39 . Nerve wave is not electricity wave , but very rapid chemical changes in the neural network . Nerve impulses that transmit images to the brain from our eyes move at speeds close to 250 miles per hour .
40 . When born , we have 300 bones . However , as adults we only have 206 bones . What exactly is happening ? Apparently, a lot of bones in our body are fused along with the growth of our body . Examples of this are the fused bones of the skull and spine .
41 . Most of us have 12 pairs of ribs . However , approximately 5 % of the population has an extra pair of ribs .
42. Shortest bone in our body is the stirrup bone located in the inner ear. This bone has a length of only 1/8 inch. While the longest bones in our body is the femur, the length varies for each person. However, the average length ranging from 1/4 height of the person.
43. There are 54 bones in the entire wrist, hand, and fingers. While in both feet, ankles, and toes are only 52 bones.
44. Foreskin of circumcised babies can grow from the size of a postage stamp to be 3 times the area of the basketball court. It is a miracle of science. Laboratory regenerate skin to replace skin burns victims.
