EXCRETORY SYSTEM Functions: The excretory system takes wastes out of the blood and removes it from the body Responsible for keeping salt level, water level, water content, and acid/base in balance The kidneys, lungs, and skin all play major roles within this system Major Organs: Carbon dioxide is excreted by the lungs and many substances are excreted through the sweat gland of the skin The kidneys are the main organs that filter about 1200mL of blood per minute - All of our blood is filtered approximately 10 times per day - Renal activities take blood to the kidneys to get filtered - Millions of blood filtering units called nephrons are responsible for this - Water, salts, and minerals are removed by each nephron - Before the waste can be removed from the body, 99% of the water is removed from the nephron - The waste is then removed within concentrated liquid waste called urine - Filtered blood will then return to the heart via renal veins Urinary Track: The urinary tract is the path taken by urine as it exits within the body
