    Study Notes

    The Urinary System

    • The urinary system eliminates waste products from the body.
    • The body takes in food and liquids, but not all are absorbed.
    • Unnecessary materials are eliminated as waste.
    • Waste buildup can be harmful, hence the need for removal systems.
    • Kidneys are bean-shaped organs that filter blood.
    • Kidneys remove waste substances like water, salts, and urea.
    • Kidneys contain thousands of filters (nephrons) that process blood ~300 times a day.
    • Urine is the liquid waste filtered by the system.
    • Ureters carry urine from the kidneys to the bladder.
    • The bladder stores urine temporarily.
    • Urine leaves the body through the urethra.
    • The urethra has a sphincter muscle to control urine flow.
    • Urination is the process of eliminating urine.
    • The amount of urine varies based on fluid intake and perspiration.
    • The nature of urine (color and odor) can vary based on consumed liquids.
    • Healthy urinary system habits promote good health, including adequate water intake and healthy eating.
    • Avoiding excessive salt intake protects kidneys from strain.
    • Regular exercise helps remove wastes through sweating and exhaling.

    How the Urinary System Works

    • The kidneys filter blood, removing waste substances.
    • Waste is excreted from the body by the urinary system
    • Useful materials are retained in the blood.
    • The filtration process removes excess water, salts, urea, and other wastes.
    • Blood is circulated to the kidneys and then to the lungs for oxygen uptake.

    How to Take Care of the Urinary System

    • Drink plenty of water (8-10 glasses daily) to help flush out waste.
    • Eat a balanced diet, avoiding excessive salt intake.
    • Eat lots of fruits and vegetables (fiber-rich foods).
    • Exercise regularly to remove wastes via sweating.
    • Avoid holding urine as this can be harmful..
    • Get enough sleep and rest.

    Urinalysis

    • Urinalysis is a way to assess kidney function and diagnose possible urinary diseases.
    • It involves analyzing urine samples, providing information regarding potential underlying issues.
    • More information on urinalysis is not provided in the text excerpt.
