Human Anatomy & Physiology Explained
,Human Anatomy and Physiology is the study of the structure and function of the human body.
These two areas work together to help explain how the body is organized and how it
performs essential life processes.
• Anatomy studies body structures and their relationships.
• Physiology studies how body parts function and work together.
Understanding anatomy and physiology is essential in healthcare, nursing, medicine, biology,
and physical therapy because it explains how the body maintains life and responds to disease
or injury.
