💧 Primary Functions of the Urinary System
The urinary system helps maintain homeostasis by:
• Removing metabolic wastes
• Regulating fluid balance
• Maintaining electrolyte balance
• Controlling blood pressure
• Regulating blood pH
• Producing urine
🧬 Major Organs & Structures
• Kidneys – filter blood and form urine
• Ureters – carry urine from the kidneys to the bladder
• Urinary bladder – stores urine
• Urethra – carries urine out of the body
📌 The kidneys are the main organs of filtration.
🔄 Urine Formation Process
Filtration – blood is filtered in the kidneys
Reabsorption – useful substances returned to the blood
Secretion – wastes added to urine
Excretion – urine leaves the body
