Fact of Human Body

The human body has a wide  regulatory system , transpiration , coordination included into the overall biological aspects that work in balance with each other . The human body  gave the outstanding performance. 24 hours a day in a system tool organs continue to work relentlessly controlled by certain nerves and keep working even when you are asleep . Did you know that even the body's systems are very complex ? You can assume such a traffic in big cities like Jakarta, assume the blood is the object in the traffic . But the difference of traffic system blood never collide with each other or in a stalemate between the goal to goal sharing.

          The circulatory system includes the heart , blood vessels and other vital network functions to fight disease and homeostasis ( maintaining the balance of temperature and pH ) . The main function of the circulatory system is to mengankut blood , nutrients , hormones and gases to and from cells throughout the body .Here 's an interesting fact that you might not ever know .11 . Channel circulatory system very longIf you can pick and sort the adult human vascular system from the base to the tip , so you can make the length is 60,000 miles ( 100.0000 km ) . 80 % are of the capillary blood vessels , which are the smallest blood vessels are .For comparison , the earth's circumference is 25,000 miles ( 40,000 km ) , meaning that the human vasculature can be 2.5 times around the earth .10 . The red blood cells , always passing through blood vesselsSmall capillaries , has an average width of about 8 microns ( 1/3000 inch ) , or about one-tenth of the diameter of the hair manusia.Ukuran hambir same as red blood cells , so that the red blood cells should be moved one by one , as the who are queuing .Some capillaries have small size lebi again , forcing the red blood cells to change their physical shape to be able to pass through.9 . Increasingly Great Body Slow The Heart RateIn the animal kingdom , the heart rate is inversely related to body size : In general , the larger the animal , the slower the heart rate of her .An adult human has an average heart rate of about 75 beats per minute , about the same as heart rate adult sheep .But the heart of a blue whale is the size of a car , his heart rate could reach an average of 1,000 beats per minute .8 . Heartbeats Not Requiring Body .If you 've seen the still beating heart of the show though outside the body , it is kenyataaan . Jatung can beat , because it produces its own electrical impulses . As long as the heart is receiving enough oxygen , the heart can still beat though terpidah of the body .7 . Man Has Heart Study Since Thousands of Years .The writings of the early circulatory system already exists in the Ebers Papyrus , an Egyptian medical document of the 16th century BC . This papyrus is believed to describe the physiological relationship between the heart and arteries , which states that once a person breathes air into the lungs , the heart and into the air then flows into the arteries . ( Still do not yet know the function of red blood cells )Interestingly , the ancient Egyptians were cardiocentric , they believe the heart , not the brain , is the source of emotions , wisdom and memory . In fact , during the mummification process , they carefully took the liver , heart and other organs to be stored , but suck the brain through the nose and throw it away .6 . During the year 1500 , Doctor Following the Wrong ModelIn the 2nd century AD , the Greek physician and philosopher Galen of Pergamon introduced perdaran blood system . He's right about that system involving venous ( dark red ) and arterial blood ( red ) , and that the two types have different functions .However , he also argues that there are two circulatory systems ( for arteries and veins ) rather than as a single entity . The liver is an organ that consumes vein and he also thought the heart was the organ to suck blood , not as pumpa .Galen theory is used as the foundation of Western medicine until the 1600s , until the English physician William Henry correctly describe blood circulation .5 . Cells Red Blood Cells Is A SpecialUnlike most other cells in the body , red blood cells have no nucleus . Less internal structure of large , each red blood cell has more room to carry oxygen the body needs . But without a nucleus , the cells do not divide or synthesize new cellular components .After circulating in the body for about 120 days , red blood cells will die due to aging or damage . But do not worry - your bone marrow constantly produces red blood cells to replace those that die .4 . Disconnect Love Can Make a Broken Heart .Broken Heart ( heart ) is a condition that can actually happen when you breakup . A condition called stress cardiomyopathy , Because of the heart muscle ( myocardium ) you suddenly weakened . This causes symptoms similar to those of a heart attack , including chest pain , shortness of breath and pain in the arm .This condition is also known as " broken heart syndrome " because it can be caused by an emotionally stressful event , such as death of a loved one or divorce , separation or physical separation from loved ones .3 . Breakthrough Science Circulatory Because Experiment In SelfCardiac catheterization is a common medical procedure that is used to this day , using the insertion of a catheter ( a long, thin tube ) into a blood vessel and sent to the patient's heart . Doctors can use this technique to perform a number of diagnostic tests on the heart , including measuring oxygen levels in different parts of the organ and check the blood flow in the coronary arteries .German physician Dr. Werner Forssmann discovered this procedure in 1929 - when he did it to himself .2 . Indeed Blood Have Different Colors ( but no blue )Oxygen -rich blood flowing through the arteries and capillaries bright red . After giving up oxygen to the tissues of your body , your blood becomes dark red when it returns to your heart through your veins .Although the blood vessels sometimes look blue through your skin , it's not because your blood is blue . The color of your blood vessels deceptive results of how different wavelengths of light that penetrate your skin , is absorbed and reflected back to your eye .But that does not mean there is no blue blood . Blood molluscs and some arthropods do not have hemoglobin which gives red color such as human blood , but containing protein hemocyanin . This makes blood instead becomes dark blue when their blood to carry oxygen .1 . Influential Living Beyond Space On Openness CirculatoryOn Earth , a person's blood tends to flow to the foot due to gravity ( the leg veins have valves that help to maintain blood flow from the legs back to the heart ) .Things are different when in outer space . Blood gathered at the chest and head ( a phenomenon called fluid shifts ) , causing astronauts experience nasal congestion , headache and facial swelling . This fluid shift also causes the heart to increase in size so it can handle the increased blood flow in organs surrounding area .Although the body has the same amount of fluid as before , the brain and other body systems interpret fluid shifts as a sudden increase in the overall fluid . As the body uses several different processes to get rid of excess fluid , resulting in an overall reduction in circulating blood volume .
