Excretory System

Toxic substances must be eliminated ex. Carbon dioxide (waste combustion of carbs and fats) nitrogenous waste (combustion of proteins)

Excretion Process by which waste products are eliminated. Mainly: lungs, kidneys, sweat glands

Sweat Glands 2 500 000 sweat glands on our surface. Helps our bodies keep a constant temperature (hot weather, exercise) Composed of water, waste materials

Urinary System Kidneys, the ureters, bladder, urethra Filters blood to remove urea, nitrogenous waste, excess water and mineral salts

Kidneys Dark red, bean shaped Eliminates waste and maintain blood balance Filter blood-Nephrons-millions, small filtration unit See table 6.48, p.192

Urine Waste from oxidation of amino acids (urea and water) Maintain water and mineral content in the blood. Excess water Water, urea, minerals, excess substances (protiens etc.) See p. 193
