  1. Sponge # 10 • What happens if the indigestible material in the large intestines moves through it too quickly? Too slowly? • When oxygen-poor blood travels to the lungs, what is the waste product it is dropping off? What is it picking up? • What part of the mouth uses mechanical digestion? Chemical? • Where does digestion start?

  2. What happens if the indigestible material in the large intestines moves through it too quickly? Too slowly? • Diarrhea • Constipation 2. When oxygen-poor blood travels to the lungs, what is the waste product it is dropping off? What is it picking up? • Carbon Dioxide (CO2) and water vapor • Oxygen 3. What part of the mouth uses mechanical digestion? Chemical? • Teeth • Saliva 4. Where does digestion start? • Mouth

  3. List any non-solid wastes in your body that comes to your mind.

  4. KEY CONCEPTThe excretory system removes wastes and helps maintain homeostasis.

  5. skin lungs kidneys ureters urinary bladder urethra • Nonsolid wastes are eliminated through lungs, skin, and kidneys. • Lungs • exhale carbon dioxide and water vapor. • Sweat • glands in skin release excess water and salts. • Kidneys • filter and clean the blood to produce urine.

  6. The Bladder stores urine • Ammonia is the toxic product produced when the body breaks down amino acids for energy • It is removed from the body by the kidneys

  7. Kidneys have three basic functions in maintaining homeostasis. • remove waste from blood • help to maintain electrolyte, pH, and fluid balances • release key hormones
