Introduction to the Urinary System

Overview

• Understanding the structure and function of the urinary system.
• Processed food and byproducts.
• Importance of eliminating toxic substances from the body.

Digestive Process and Byproducts

• Food is broken down through the digestive system:
  • Proteins into amino acids.
  • Byproducts include carbon dioxide, water, and ammonia.
• Ammonia is toxic in high amounts.
• Carbon dioxide and fats also produce byproducts.

Role of Respiratory System

• Majority of carbon dioxide is expelled through breathing.
• Remaining carbon dioxide can convert to carbonic acid.

Functions of the Urinary System

• Blood Cleaning: Removes waste from the blood.
• pH Regulation: Eliminates carbonic acid to maintain pH balance.
• Blood Pressure Regulation: Maintains proper blood pressure to avoid complications.
• Homeostasis: Overall maintenance of balance in the internal environment.

Components of the Urinary System

1. Kidneys
   • Key role in filtration and urine production.
2. Ureters
   • Tubes transporting urine from kidneys to bladder.
3. Bladder
   • Stores urine until expulsion.
4. Urethra
   • Channel for urine to exit the body.

Processes in the Kidneys

• Filtration: Filtering blood to remove waste.
• Reabsorption: Returning necessary substances back to the blood.
• Secretion: Adding more waste to the urine.
• Elimination: Expelling urine from the body.

Mnemonic to Remember Processes

• F.R.S.E: "Funny Reptile Sings Everything"
  • F: Filtration
  • R: Reabsorption
  • S: Secretion
  • E: Elimination

Conclusion

• The combination of these processes leads to the formation of urine.
