Human Anatomy and Physiology

Human anatomy is the study of the structure of the body’s parts—bones, muscles, organs, and tissues—while physiology examines how these parts work individually and together to support life. The skeletal system provides a framework, the muscular system enables movement, and organs like the heart, lungs, liver, and kidneys perform vital functions such as pumping blood, breathing, and removing waste. These systems operate in harmony through complex interactions, regulated by the nervous and endocrine systems, maintaining balance (homeostasis). Understanding anatomy and physiology helps us comprehend how the body functions and how to maintain health.
