Fascinating Facts About Human Body

Fascinating Facts About Human Body

1. The Skeletal System 
-  The largest bone is the pelvis, or hip bone. In fact it is made of six bones joined firmly together.
-  The longest bone is the 'femur', in the thigh. It makes up almost one quarter of the body's total height.
-  The smallest bone is the 'stirrup', deep in the ear. It is hardly larger than a grain of rice.
-  The ears and end of the nose do not have bones inside them. Their inner supports are cartilage or 'gristle', which is lighter and more flexible than bone. This is why the nose and ears can be bent.
-  After death, cartilage rots faster than bone. This is why the skulls of skeletons have no nose or ears.


2. The Muscular System
-  There are about 60 muscles in the face. Smiling is easier than frowning. It takes 20 muscles to smile and over 40 to frown.
-  The longest muscle in the body is the sartorius, from the outside of the hip, down and across to the inside of the knee. It rotates the thigh outwards and bends the knee.
-  The smallest muscle in the body is the stapedius, deep in the ear. It is only 5mm long and thinner than cotton thread. It is involved in hearing.
-  The biggest muscle in the body is the gluteus maximus, in the buttock. It pulls the leg backwards powerfully for walking, running and climbing steps.


3. The Circulatory System 
-  The heart beats around 3 billion times in the average person's life.
-  About 2 million blood cells die in the human body every second, and the same number are born each second.
-  Within a tiny droplet of blood, there are some 5 million red blood cells, 300,000 platelets and 10,000 white cells.
-  It takes about 1 minute for a red blood cell to circle the whole body.
-  Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die.
-  Red blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells.


4. The Nervous System 
-  The brain looks like a giant, wrinkled walnut.
-  Unlike other body cells, brain cells can not regenerate. Once brain cells are damaged they are not replaced.
-  The brain and spinal cord are surrounded and protected by cerebrospinal fluid.


5. The Immune System
-  The skin secretes antibacterial substances. These substances explain why you don't wake up in the morning with a layer of mold growing on your skin - most bacteria and spores that land on the skin die quickly.
-  Tears and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria.
-  Lymph nodes contain filtering tissue and a large number of lymph cells. When fighting certain bacterial infections, the lymph nodes swell with bacteria and the cells fighting the bacteria, to the point where you can actually feel them. Swollen lymph nodes may therefore be a good indication that you have an infection of some sort.


6. The Digestive System 
-  Adults eat about 500 kg of food per year.
-  1.5 litres of saliva are produced each day.
-  The oesophagus is approximately 25cm long.
-  Muscles contract in waves to move the food down the oesophagus. This means that food would get to a person's stomach, even if they were standing on their head.
-  An adult’s stomach can hold approximately 1.5 litres of material.
-  Every day 11.5 litres of digested food, liquids and digestive juices flow through the digestive system, but only 100 mls of fluid are lost in faeces.
-  In the mouth, food is either cooled or warmed to a more suitable temperature.
-  We get two sets of teeth. Our 20 'Baby Teeth’ are replaced starting at around 6-7 years of age with our 32 ‘Adult Teeth’.


7. The Respiratory System
-  At rest, the adult body takes in and breathes out about 6 litres of air each minute.
-  The right lung is slightly larger than the left.
-  Hairs in the nose help to clean the air we breathe as well as warming it.
-  The highest recorded "sneeze speed" is 165 km per hour.
-  The surface area of the lungs is roughly the same size as a tennis court.
-  The capillaries in the lungs would extend 1,600 kilometres if placed end to end.
-  We lose half a litre of water a day through breathing. This is the water vapour we see when we breathe onto glass.
-  A person at rest usually breathes between 12 and 15 times a minute.
-  The breathing rate is faster in children and women than in men.

Body Piercing - Know The Risks

Body Piercing - Know The Risks

Traumatic tear of the earlobe

Having a part of your body pierced is a very important decision and can have negative health effects if done poorly.If you are considering having a piercing done read on and check out some of the facts for yourself.

Tongues, Lips and Cheeks

Although popular, these can be some of the more dangerous areas of the body to get pierced. Complications can include infections, speech impediments, breathing problems, increased tooth decay and broken teeth. Infections can result in blood poisoning, toxic shock syndrome, a blocked airway, as well as the risk of diseases like HIV and hepatitis.

Eyebrows, nose, ear Lobes and upper ears

Infections in the area around the eyes and nose can result in serious complications. Pierced ear lobes have been around for hundreds of years. Recently, the trend is towards piercing the upper ear through the cartilage that gives your ear its structure. Ear cartilage is sensitive and slow healing. Infections can cause a
‘cauliflower’ appearance of the ear. Piercing the side of your nose can also be very painful, and can cause difficulties if you have a cold or runny nose.

NippLes and naveLs
Nipple piercing in women can create scar tissue that may cause difficulties in breast-feeding in later life. The nipple is very sensitive and therefore can be very painful to pierce. Bellybuttons also should be pierced with care and watched constantly. The moist,  warm nature of the navel makes risk of infection a little higher.

Genitals
Piercing genitals is a decision that should not be taken lightly. An infection here is not only painful, but can be very serious. It is really important to try and get some advice from a doctor before considering piercing of the penis, labia, clitoris, foreskin or scrotum. Some States and Territories restrict access to these procedures to those aged 18 years and over.

HIV and other diseases
There are also significant risks of transmission of diseases like hepatitis B and C and HIV/AIDS in unsafe piercing studios and with piercing done by friends or relatives in un-sterile conditions. It is essential that any sign of infection is treated seriously and promptly.

After the procedure
The body piercing provider should provide you with information about how to care for your new piercing. Remember to make an immediate appointment with your doctor if there are any problems with an area that is pierced that might indicate infection or complications (such as bleeding, pain, weeping or swelling), or that you are worried about.

It is also important to remember that you can talk to your doctor before you decide to have any area of your body pierced.
You doctor will be able to: 

•   discuss the risks with you; 
•   warn about possible allergies, infections and abnormal “keloid” scarring; 
•   tell you how to make sure that the piercing  studio is safe; 
•   talk about how to care for your piercing; and 

  show you what to look for and what to do if something goes wrong.
Some doctors are happy to do piercing for their patients in a clean, sterile and safe environment. Remember your doctor can also give you another opportunity to discuss your decision further. Drugs and alcohol can impair decision making so do not get a piercing done while under the influence. It is best to give yourself some time to think through your decision to get a piercing.
