The term that describes the proper balance of fluid and chemicals in the body is homeostasis. Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in external conditions. This includes regulating temperature, pH, and the concentration of various substances, such as electrolytes and fluids, which are essential for cellular function and overall health.

Homeostasis is a dynamic process that involves multiple organ systems working together to achieve balance. For example, the kidneys play a crucial role in filtering blood and regulating fluid and electrolyte levels, while hormones can adjust these parameters as needed to respond to the body's requirements.

The other terms, while they have relevance in the context of health and body functions, do not specifically encompass the entire concept of maintaining a balanced internal environment. Hydration specifically refers to the process of providing adequate fluid to the body. Equilibrium, while similar, is more generic and does not capture the ongoing regulatory processes that occur within living systems. Osmosis is a specific physical process involving the movement of water across a semipermeable membrane, which is a part of how fluid balance is achieved but does not represent the overall concept of balance in the body.
