This document discusses 5 organs that are essential for life: the liver, kidneys, lungs, heart, and brain. The liver performs many important functions like bile production, metabolizing nutrients, and filtering toxins from the blood. Liver failure can cause complications like infection, electrolyte imbalances, and bleeding, which can ultimately lead to death without treatment. The kidneys control fluid balance, filter waste, and remove toxins from the blood. Lung failure prevents the exchange of oxygen and carbon dioxide in the bloodstream. The heart pumps blood throughout the body and maintains blood pressure. Brain death means the brain has completely stopped functioning and cannot be reversed, defining the legal definition of death.

2. INTRODUCTION
There are 78 organ in human body some of them you can live
without e;x (appendix, spleen) but of course if they absent,
cause many problem but still you can live, but there is five organ
if you lost it you cannot live anymore.

LIVER KIDNEY LUNG HEART BRAIN

4. WHAT IS LIVER
Shaped like a cone, the liver is a dark reddish brown organ
that weight about 3 pounds.There are 2 distinct sourses that
supply blood to the liver including the following: oxygenated
blood flows in from the hepatic artery. Nutrient- rich blood
flow in from the hepatic portal vein.

5. MAIN FUNCTION OFTHE LIVER
Bile production and excretion.
Excretion of bilirubin, cholesterol, hormones, drugs.
Metabolism of fats, protein and carbohydrate.
Enzyme activation.
Storage of glycogen, vitamins and minerals.

6. IF LIVER DON’TWORK
Liver failure can affect many of your body’s organ. Acute liver
failure can cause such complication as infection, electrolyte
deficiencies and bleeding without treatment both acute and
chronic liver failure may eventually result in death.
So that’s why liver is very important organ and liver failure without
treatment is dangerous.

7. WHAT IS KIDNEY
The kidney are two bean shaped organs, each about the
size of a fist.They are located just below the rip cage one
on each side of your spine.

8. KIDNEY FUNCTION
Controlling ACID base balance.
Controlling water balance.
Maintaining electrolyte balance.
Removing toxins and waste products from the body.
Controlling blood pressure.
Activating vitamin D

9. IF KIDNEY DON’TWORK
Still one kidney can do his job without problem but if both of
your kidney don’t work completely your body fill with extra
water and waste products.This condition is called uremia,
your hands or feet may swell.You will feel tired and weak
because your body needs clean blood to function properly.
So that’s why kidney is one of important organs.

10. WHAT IS LUNG
Lungs are one of a pair of organ in the chest, and part of
respiratory system, a group of organs and tissues that
work together to help you breath.

11. LUNGS FUNCTION
They bring oxygen into our bodies (called inspiration or
inhalation) and send carbon dioxide out (called expiration or
exhalation).
Warms air to match your body temperature and moisturizes to
the humidity level your body needs.
Protects your airways from harmful substances and irrirants.

12. IF LUNGS DON’TWORK
The condition or injury may affect your airways or lungs. Or it
may affect the muscles nerves and bones that help you
breath.When you can’t breath well, your lungs can easily
move oxygen into your blood or remove carbon dioxide this
causes a lo3w oxygen or high carbon dioxide level in your
brain. So it make lungs very important for body.

13. WHAT IS HEART
The heart is a pump, usually beating about 60 to 100 times
per minute.With each heartbeat, the heart sends blood
throughout our bodies, carrying oxygen to every cell….The
heart then sends the blood to the lungs to pick up more
oxygen.

14. HEART FUNCTION
Pumping oxygenated blood to the other body parts.
Pumping hormones and other vital substances to different
parts of the body.
Receiving deoxygenated blood and carrying metabolic waste
products from the body and pumping it to the lungs for
oxygenated.
Maintaining blood pressure.

15. IF HEART DON’TWORK
Heart failure occurs when the heart muscle doesn’t pump
blood as well as it should. Blood often backs up and causes
fluid to build up in the lungs and in the legs.The fluid build up
can cause shortness of breath and swelling of the legs and
feet.
We can say heart is the very main organ. you can live with
heart failure

16. BRAIN AND FUNCTION
The brain is the complex organ that controls through memory,
emotion, touch, motor skills, vision, breathing, temperature,
hunger and every process that regulates our body.Together
the brain and spinal cord that extends from it make up the
central nervous system or CNS.

17. IF BRAIN DON’T WORK
Brain death is a legal definition of death. It is the complete stopping.
Of all brain function and cannot be reversed. It means that because of
extreme and serious trauma or injury to the brain, the body’s blood
supply to the brain blocked, and then dies. Brain death is death.
So we can say brain is most main organ in the body. Any problem in
any part of brain affect a part of your body.
