Genitourinary System: Anatomy & Physiology

In this episode of TechPrep: Rapid PTCB Review, we review genitourinary anatomy and physiology with a focused, exam-relevant approach tailored to pharmacy technician practice and the PTCB exam. Learners will explore the structure and function of the kidneys, urinary tract, and related systems, and how these components work together to maintain fluid balance, electrolyte regulation, and waste elimination.

The episode connects GU anatomy and physiology to medication therapy by introducing common genitourinary conditions and the role of the kidneys in drug clearance. Emphasis is placed on why renal function is critical in dosing, medication safety, and preventing toxicity—key concepts for pharmacy technicians.
