Human Urinary System Anatomy Diagram | Medical Education Resource #30721 (License: Personal Use)

This black-and-white medical illustration depicts the core components of the human urinary system: two kidneys filter blood to produce urine, which travels via the paired ureters to the bladder for storage. The bladder connects to the urethra through the sphincter, which controls urination. Labels are clearly placed for educational clarity.

Used in medical textbooks, online anatomy courses, patient education materials, and healthcare websites to explain urinary physiology and pathology; matches user intent for learning or teaching basic urological anatomy.
