    Life Science 3.2 : The Urinary System Life Science 3.2 : The Urinary System Presentation Transcript

    • Life Science 3.2
      The Urinary System
    • Objectives:
      Describethe parts and functions of the urinary system.
      Explain how the kidneys filter blood.
      Describe three disorders of the urinary system.
    • Cleaning the Blood
      The urinary system contains the organs that remove waste products from your blood.
    • The Kidneys as Filters
      Kidneys
      Pair of organs in the urinary system that clean the blood and excrete products as urine.
      Inside each kidney are more than 1 million microscopic filters called nephrons.
    • Water In, Water Out
      Sweat and Thirst
      The evaporation of water sweat cools you down.
      As the water content of the blood drops, the salivary glands produce less saliva, resulting in thirst.
      Antidiuretic Hormone
      When you get thirsty, antidiuretic hormone is released.
      This hormone signals the kidneys to take water from the nephronsand return it to the body.
      Diuretics
      Cause the kidneys to make more urine, which decreases the amount of water in the blood.
      Example: beverages containing caffeine
    • Urinary System Problems
      Bacterial Infections
      Bacteria can get into the bladder and uretersthrough the urethra and cause painful infections.
      Kidney Stones
      Salts and other wastes can collect inside the kidneys and form kidney stones.
      Kidney Disease
      Damage to nephrons can prevent normal kidney functioning and can lead to kidney disease.
