Physiology for Nursing Exam Practice Tests
Course Introduction
Physiology for Nursing provides an in-depth understanding of the normal functioning of the human body, with an emphasis on mechanisms that maintain homeostasis across all major organ systems. This course covers the physiological concepts essential for nurses, including cellular processes, neuroendocrine regulation, cardiovascular and respiratory dynamics, renal function, digestion, and reproductive physiology. Through lectures, discussions, and case studies, students learn how physiological principles relate to clinical assessments and interventions, preparing them to apply this knowledge effectively in diverse healthcare settings.
