Did you know that a deviation of just a few degrees in body temperature or a small shift in blood pH can be life-threatening? The human body's remarkable ability to maintain a stable internal environment, known as homeostasis, is fundamental to life and overall health. This article will explain why it is important to control homeostasis of pH and body temperature.

The human body is approximately 60% water, and this fluid is distributed across two major compartments. Understanding **what's the difference between ICF and ECF** is crucial, as these compartments, the intracellular fluid (ICF) and extracellular fluid (ECF), play distinct yet interconnected roles in cellular function and overall health.

Intracellular fluid (ICF) constitutes approximately two-thirds of your body's total water content, highlighting its sheer physiological importance. This vital substance, found within every cell, is the dynamic environment where all life-sustaining biochemical reactions take place. Understanding **what is the main function of intracellular fluid** is essential for grasping the fundamental mechanisms that keep us alive.

The average adult human body is made up of approximately 50-60% water, a carefully regulated balance essential for life. This leads to the intriguing, and somewhat alarming, question: what happens if your body is 100% water? This article will explore the physiological impossibility and the dire consequences of such a state.

The human brain contains approximately 86 billion neurons, each with a nucleus at its core acting as a vital control center. This central organelle orchestrates all cellular activities, providing the genetic instructions that define and regulate nerve cell function. Understanding **what is the role of the nucleus in the nervous system** is foundational to comprehending everything from basic nerve impulses to complex cognitive processes.
