=__Which specific human body organs help protect the body against toxins?__=

//** The four main organs that protect the body against toxins are lungs, kidneys, liver, and the skin. This system is called the Excretory System. Excretion means to remove waste from an organism. If the waste builds up it could poison the body. **//

=__ Liver: __=

//** The liver is one of the four major organs that gets rid of toxins from the body. The liver detoxifies harmful substances whether they come from internal or external sources. It has to convert fat soluble toxins into water soluble substances that can be excreted from the body. The liver plays several roles in detoxification. First it filters the blood to remove large toxins. Then gets rid of bile full of cholesterol and other fat-soluble toxins, and then eliminates unwanted chemicals. **// = = =__ Kidneys: __=


 * // To eliminate toxins, your kidneys perform a number of vital functions. First it has to filter waste products out of the bloodstream, which are then removed from your body through urine. Your kidneys are made up of Nephrons, each of which contains a filtering unit of tiny blood vessels. Then most of the fluid is returned to your bloodstream, but about two quarts, which contain waste products that your body can’t use such as caffeine and alcohol, is mixed with excess water and the excreted out of the body. //**



=__ Lungs: __=

//** The lungs are a part of the respiratory and excretory system. Air is breathed into the lungs, and a gas exchanged takes place. The oxygen will then release to living cells. The cells need oxygen so they can carry on respiration. Which is the releasing of energy from food and oxygen in the individual cells. The waste is then carried back to the lungs and eliminated from the body. **//

=  = = = =__ Skin: __=

//** The skin is the largest organ in the body. The last member of the Excretory system. There are two main layers of the skin. The outer layer is called the Epidermis, the surface cells of this layer are dead, they are constantly being rubbed off and being replaced by cells beneath them. Under that layer is called Dermis, the cells in this layer are all alive, it contains blood vessels, sweat, and oil glands. **//
