Anatomy is a branch of biology that focuses on studying the physical structure of living organisms. In particular, it explores how the parts of an organism are built and how they function together. When combined with physiology and biochemistry, human anatomy becomes a foundational part of medical science.

The human body has many intricate systems, each playing a crucial role. For instance, the circulatory system includes the heart and blood vessels, and its functions are vast. This system is responsible for moving blood throughout the body, delivering nutrients, removing waste, and transporting immune and clotting cells. It’s also closely connected to the lymphatic and immune systems, showing how our body’s systems work hand-in-hand.

In essence, no single part of our anatomy works entirely alone. Every component relies on others to ensure the body operates smoothly and efficiently.
