ANATOMY AND PHYSIOLOGY 1

Anatomy and Physiology are key subjects that explain how the human body is structured and how it functions. Anatomy focuses on the physical parts of the body—such as organs, tissues, and systems—while physiology explains how those parts work together to keep us alive and healthy. The body is organized in levels, from basic chemical building blocks to complex organ systems. Understanding anatomical positions, directional terms, and body cavities helps in describing locations accurately in clinical settings. Learning about cells, genetics, and how body systems maintain balance (homeostasis) is essential for assessing health, diagnosing conditions, and delivering effective patient care.

The cardiovascular system transports blood, delivering oxygen, nutrients, and hormones while removing waste. It includes the heart, blood vessels, and blood, which consists of plasma, red and white cells, and platelets. This unit also covers blood types, clotting, heart function, circulation, and the lymphatic system’s role in immunity.

The musculoskeletal system provides structure, movement, and protection through bones, muscles, joints, and connective tissues. It supports vital functions like blood cell production, mineral storage, and posture. Understanding bone and muscle structure, development, and function is essential for diagnosing injuries, disorders, and maintaining overall health and physical performance.
