📖 1. Urinary System Functions

🔑 Key Concepts & Definitions

• Excretion: The removal of organic wastes from body fluids (UNIVERSITY OF TECHNOLOGY, JAMAICA). It involves eliminating metabolic byproducts and other wastes that are present in body fluids, preventing their accumulation and potential toxicity.

• Elimination: The discharge of waste products (UNIVERSITY OF TECHNOLOGY, JAMAICA). It is the process by which waste substances are expelled from the body, primarily through the urinary system via urination.

• Homeostatic regulation of blood plasma volume and solute concentration: The process by which the urinary system maintains stable blood volume and solute levels, ensuring proper physiological balance. This involves adjusting water and solute excretion to match intake and metabolic needs (UNIVERSITY OF TECHNOLOGY, JAMAICA).

📝 Essential Points

• The urinary system's primary functions include excretion of organic wastes, elimination of waste products, and homeostatic regulation of blood plasma volume and solute concentration.
