7. LIVER-THE LIVER ALSO DETOXIFIES CHEMICALS AND METABOLIZES
DRUGS. AS IT DOES SO, THE LIVER SECRETES BILE THAT ENDS UP
BACK IN THE INTESTINES. THE LIVER ALSO MAKES PROTEINS
IMPORTANT FOR BLOOD CLOTTING AND OTHER FUNCTIONS.

NEPHRON FILTERS A SMALL AMOUNT OF BLOOD
The kidneys

12. CURES FOR KIDNEY DISEASE
Kidney diseases can not be cured when the
kidneys are damaged they can not be
repaired treatment focuses on slowing the
disease and preventing complications
* One complication is high blood pressure
(hypertension) which damages the kidneys
* With kidney disease you can lose proteins
in urine
