Muscles are the "machines" of the body. Skeletal muscles allow for locomotion and facial expressions, while cardiac and smooth muscles handle internal transport. The Nervous System

Also known as the excretory system, it removes nitrogenous wastes from the blood and maintains the body’s water and salt balance. The Reproductive System human anatomy and physiology

At the center lies the heart, a four-chambered pump. The vascular system includes arteries (carrying blood away from the heart), veins (returning blood to the heart), and capillaries (tiny vessels where exchange occurs).

The adult human skeleton consists of 206 bones, ranging from the tiny stirrup bone in the ear to the massive femur in the thigh. It also includes cartilage, ligaments, and joints. The skeleton is divided into the axial skeleton (skull, spine, ribs) and the appendicular skeleton (limbs). The Reproductive System At the center lies the
