Understanding Body Waste: Causes and Removal

Sources of Body Waste

  • Metabolic waste: CO₂, water, urea, nitrogen compounds from energy production.
  • Cellular debris: Dead cell remnants.
  • Toxins: Environmental and internal.

Elimination Systems

  • Respiratory: Lungs exhale CO₂, water vapor.
  • Kidneys: Filter blood → urine.
  • Liver: Processes waste, detoxifies blood.
  • Digestive: Eliminates solid waste (feces).
  • Skin: Sweat excretes water, electrolytes, waste.

These systems maintain fluid/electrolyte balance. Dysfunction causes waste buildup and health problems.
