Why do I have a..

Heart??
Your body's engine the heart pumps blood to every cell in your body.

Blood??
A mix of special cells and liquid "plasma". Blood delivers all the good stuff (oxygens, vitamins, minerals, and chemicals called hormones)  to the cell in your body and carries away the bad stuff (CO2 and other waste) for disposal. Red blood cells transport oxygen, while white blood cells  fight infection.special  cells called platelates Del the leak when blood vessels break -- a process called clotting. An oxygen carrying protein called hemoglobin is what gives blood it's red color.

Lungs?? 
Each breath you inhale fills these balloon-like organs with oxygen, which is absorbed into your blood: each exhalation expels CO2 from your blood.

SKIN?? 
Skin holds your insides in and protects your tissues from ultra-violet radiation from the outside. Skin in your body's largest organ. It is made of layers of cells that march to the surface and flake odd from friction. The outermost layer is entirely dead.

Tonsils? ?
These two meatballs shaped masses of tissue at the back of your throat are part of your lymph system , which includes a network of nodes that work like little security guards to battle infection.

Appendix?? 
This skinny tube in our digestive system is mostly useless today and can actually endanger your life if it becomes inflamed. Scientists suspect that the  appendix which replenishes essential bacteria in our guts, was an important organs Back before germs-fighting medicines helped humans overcome constant bouts of diarrhea.

Stomach ??
This expandable organs stores everything you eat and starts breaking down food with powerful acids.

Intestines??
The bulk of food digestion takes place in your small and large intestine, two tubes that absorb all the vitamins minerals mineral, and other nutrients from everything you eat.

Liver
Your body's biggest internal organ, the liver is like a complex chemical-processing plant. It converts nutrients from the small intestine into fuel your body can use. It makes bile, an essential substance for digestion. It cleans your blood of toxins and removes damaged red blood cells.

Kidneys
This bean-shaped  organ is so essential to good health that your body comes with a second one for free! Each kidney is crammed with more that a million microscopic filters-called nephrons --that skin the waste chemicals and other gunk from your blood.

PANCREAS??
This organs inject special protein substance called enzyme into your small intestine to break down carbohydrates for facts and energy, and proteins for bodybuilding materials. The pancreas also creates a crucial hormone called insulin,  which regulates the level of sugar in your bloodstream.

SPLEEN??
This fragile fist shaped sack is your body's infection fighter, filtering bacteria, viruses and other nasty invaders from your blood.

SKELETON ? ?
Remove all your bones along with the joints and muscles pinned to them and you would end up a shapeless, motionless bag of blood and organs. Your skull and spinal vertebrae, made of tough deposits of calcium and other minerals,  are like armor for your brain and nervous system. Special bone marrow in your vertebrea and elsewhere is your body's blood factory.  Your muscles and joints,  meanwhile,  set your human machine in motion.

Do you know interesting facts......
1. About 350 bones in the body of  birth.
2. An adult person has 206 bones.
3. Length of small intestine is 20feet(6 meter)
4. Length of blood vessels is 60,000 miles(96,560 KM)
5. Average volume of blood in an adult's body is 1.3 GALLONS(5 Liter).
